SERIAL CONNECTIVITY NETWORK MODULES (NM-1HSSI, NM-4T, NM-4A/S, NM-8A/S, NM-16A/S, NM-16A, NM-32A)

Cisco Multi-Service Access Routers and Integrated Services Routers offer a wide variety of serial connectivity modules to accommodate the range of application needs in customer networks. The serial network module family assures customers that they can choose a serial connectivity solution that fits their requirements. Serial connectivity options offer several port densities, synchronous and asynchronous alternatives. As modular components, they are easily and inexpensively field upgradeable as customer requirements change.

Available serial connectivity Network Modules include:

• NM-1HSSI: One-port High Speed Serial Interface (HSSI)

• NM-4T: Four-port serial

• NM-4A/S: Four-port asynchronous/synchronous serial

• NM-8A/S: Eight-port asynchronous/synchronous serial

• NM-16A/S: 16 port asynchronous/synchronous serial

• NM-16A: 16 port high-density asynchronous

• NM-32A: 32 port high-density asynchronous

The NM-1HSSI is a single port, high-speed network module that provides connectivity to a Wide Area Network. Demand for high capacity corporate backbones, high-speed Internet access, Virtual Private Networks (VPNs), and trunking connections for service provider internetworking has led to an increase demand for clear channel DS3 and E3 connections. Also see the NM-1T3/E3 clear channel T3/E3 Network Module (http://www.cisco.com/warp/public/cc/pd/ifaa/ps4909/prodlit/ttnp_ds.htm).
The NM-1HSSI Network Module supports speeds up to 52 Mbps. The NM-1HSSI also supports fractional T3/E3 speeds from 56 kbps to 52 Mbps.

FOUR-PORT NETWORK MODULE (NM-4T)

Figure 3. Four-Port Serial Network Module NM-4T

The NM-4T serial network module has four synchronous serial interfaces. The network module supports a total full-duplex throughput of 8 megabits per second (Mbps), which can be realized over one port (at 8 Mbps) or across all four ports (at 2 Mbps on each port).
The NM-4T module in any network environment delivers very low price per port and provides higher performance than comparable third-party solutions. For instance, a small or medium-sized Internet service provider (ISP) with high serial density requirements may find this solution very cost-effective per subscriber.

HIGH-DENSITY ASYNCHRONOUS NETWORK MODULES

Figure 6. High Density Asynchronous Network Module NM-32A

The NM-16A and NM-32A network modules provide flexible, high-density asynchronous connectivity at a competitive price per port and higher performance than comparable third-party solutions. The modules support V.34 speeds at up to 4x compression (134.4 kbps) over the asynchronous connection. Three examples where this module can be deployed follow:

• Small to medium-sized power branch offices where remote users require modem dial access; a fully configured Cisco 3845 chassis with four async network modules connected to the modem rack enables connectivity for up to 128 dial-in users

• Medium-sized branch offices that require a high-density terminal server; a fully configured Cisco 3845 chassis with four async network modules connected to the modem rack (with optional custom cables) enables connectivity for up to 128 terminal connections

• Telemetry applications, connecting a NM-32A module to private branch exchange (PBX) serial ports, data collection equipment, or router consoles

Cabling

The NM-16A and NM-32A modules support two or four Cisco "octopus" cables. Each cable terminates eight ports, with optional physical endpoints of RJ-45 or DB-25. A NM-16A module requires two cables, and the NM-32A requires four cables. Table 4 shows the available cables and end connectors for use with the NM-16A and NM-32A.

Multiservice Interchange for Cisco 2600 & 3600 Series Platforms

CISCO/라우터 & 라우팅 시스템 2007/05/04 12:26

Multiservice Interchange for
Cisco 2600 and 3600 Series
Multiservice Platforms

Multiservice Interchange (MIX) adds time-division multiplexing (TDM) connection capabilities to all Cisco 2600 and 3600 platforms. MIX enables the combination of different types of traffic on a single T1 or E1 connection, allowing smooth migration from TDM voice to packet voice on one integrated platform. Customers can also save WAN bandwidth by mixing TDM voice and packet data on the same link using the Drop & Insert function (Integrated Add/Drop Multiplexing).

Introduction

With IOS software releases 12.1(5)XM1 or 12.2(1)T, Multiservice Interchange (MIX) is available on all Cisco 2600 and 3600 Multiservice platforms with Cisco 3660 platform offers the most extensive features.

MIX on Cisco 3660

MIX solution on the Cisco 3660 multiservice platform comprises a special combination of hardware and software components. The hardware consists of a multiservice interchange card, also called a MIX module (MIX-3660-64), and one or more of the Voice/WAN interface cards (VWIC), the Fast Ethernet network modules (NM-xFE2W), the High-Density Voice network modules (HDV) and the ATM OC-3 CES network modules (NM-1A-OC3XX-1V). The software is any of the Cisco IOS feature sets starting with Release 12.1(5)XM1 or 12.2(1)T.

MIX-enabled Cisco 3660 platform provides the ability to integrate voice and data on the same T1/E1 interface without the need for an external time-division multiplexing (TDM) device. The MIX module (MIX-3660-64) is designed for Cisco 3660 platform only, and it plugs into the TDM slot on the motherboard of a Cisco 3660. Cisco 3660 platform now can support up to 16Mbps of full duplex TDM switching capacity to or from a MIX enabled network module over the multiservice interchange card.

The Cisco 3660 with the installation of a MIX module (MIX-3660-64) provides:

  • TDM switching of latency and delay sensitive traffic such as voice and video across the backplane

  • Integrated Add/Drop Multiplexing (D&I) capability across different T1/E1 spans

  • DSP resource sharing across two different MIX-enabled network modules

  • ATM CES applications


Figure 1: Multiservice Interchange (MIX) Module for Cisco 3660 Series Platform (MIX-3660-64)

D&I (Integrated Add/Drop Multiplexing) on Cisco 3600

While the TDM backplane capability is only available on Cisco 3660 platform, there is an enhancement in IOS 12.1(5)XM1 or 12.2(1)T software release to the Fast Ethernet network module (NM-xFE2W) that is available on all Cisco 3600 platforms. This enhancement is the capability to do Integrated Add/Drop Multiplexing (D&I) across the ports of two Voice/WAN interface cards (VWIC) resides in the same NM-xFE2W. In the past, D&I had only been allowed between ports on the same VWIC since the introduction of the Voice/WAN Interface cards first supported on IOS release 12.0(5)XK.

MIX functionality available on Cisco 2600 and 3600 platforms are summarized in table 1 below.

1For all Cisco 2600 and 3600, D&I across two T1/E1 within the same VWIC is only supported by the following Voice/Wan Interface Cards: VWIC-2MFT-T1-DI, VWIC-2MFT-E1-DI, and VWIC-2MFT-G703.
2Only port 1 of a VWIC resident in an ATM OC-3 CES NM can also participate in D&I applications, port 0 cannot.
3A maximum of 4 E1s' worth of CES traffic can be fed into a single OC-3 card, as follows: 2 E1s from the VWIC inside the OC-3 CES NM and 2 E1s from VWIC in other NMs.

Key Benefits

  • TDM functionality allows smooth migration to packet voice—MIX-enabled Cisco 3660 platform provides the ability to integrate TDM voice, packet voice and data on the same T1/E1 interface without the need for an external TDM device. Such a solution encourages customers to put all their network traffic on one integrated platform for ease of management and lower cost of ownership. It is ideal for enterprise customers who are hesitant to cut through all their voice traffic on a packet infrastructure.

  • Allows cost-conscious customers to aggregate bandwidth and save WAN costs—With the TDM backplane, Cisco 3660 can perform D&I (cross-connection of tdm-groups) across any two VWIC ports reside on either a NM-HDV or a NM-xFE2W. Port 1of a VWIC resides in an ATM OC3 CES NM can also participate in D&I (Drop and Insert) applications. This functionality allows customers to combine voice and data using Time Division Multiplexing to "channelize" voice and data streams over a common T1/E1 or fractional T1/E1 service for reduced WAN costs.

  The enhancement in IOS 12.1(5)XM1 or 12.2(1)T releases enables all Cisco 3600 to do Integrated Add/Drop Multiplexing (D&I) across the ports of two VWICs reside in the same NM-xFE2W.
  The D&I feature provides flexible timeslot assignment from port to port on all Cisco 3600 and offers customers investment protection in migration to packet voice.
  • Maximizes system resources through DSP resource sharing across two different network modules—MIX solution enables a Cisco 3660 to connect T1/E1s carrying voice channels to a NM-xFE2W even though these network modules do not have any DSP resources to process the voice traffic. These voice channels will be mapped to DSP resources on a neighboring NM-HDV.

  • Allows service providers to quickly deliver local or long distance voice for maximum profitability by transporting the traditional PCM-encoded 64-Kbps circuit-based voice over an ATM network—Enhanced Circuit emulation service (CES) of T1/E1s can now be supported on Cisco 3660 platform through MIX. Voice channels of T1/E1 on NM-xFE2W and NM-HDV network modules can be transported across the MIX module to ATM OC-3 network modules (NM-1A-OC3XX-1V) over an ATM network. Fully interoperable with today's existing PSTN infrastructure, PVC-based (permanent virtual circuit) CES allows service providers to quickly deliver local or long distance voice, while SVC (switched virtual circuit) capabilities ensure that these services be optimized for maximum profitability.

Key Features

The Multiservice Interchange (MIX) solution on Cisco 3660 enables the following key features:

  • Connection of TDM streams between two Voice/WAN interface cards (VWICs) on the same Fast Ethernet network module (NM-xFE2W)

  Participating VWICs are:
  • VWIC-1MFT-T1, VWIC-1MFT-E1

  • VWIC-2MFT-T1, VWIC-2MFT-E1

  • VWIC-2MFT-T1-DI, VWIC-2MFT-E1-DI

  • VWIC-1MFT-G703, VWIC-2MFT-G703

  • Connection of TDM streams between separate TDM-enabled network modules

  The following network modules (NM) are currently TDM-enabled:
  • High-Density Voice

NM-HDV
  • Fast Ethernet Mixed Media (NM-xFE2W)

NM-1FE2W
NM-2FE2W
NM-1FE1R2W
NM-2W
  • ATM OC-3 CES (NM-1A-OC3XX-1V)

NM-1A-OC3MM-1V
NM-1A-OC3SMI-1V
NM-1A-OC3SML-1V
  • DSP resource sharing across High-Density Voice network modules (NM-HDV) and Fast Ethernet Mixed Media network modules (NM-xFE2W), so that unused DSPs on a NM-HDV can form a DSP resource pool to support voice traffic on NM-xFE2W across Cisco 3660 backplane

    • NM-HDV provides the DSPs

    • NM-xFE2W or other NM-HDV use the DSPs

    • ds0-groups and voice pri-groups are now supported on a VWIC in a NM-xFE2W

    • DSPs to voice channels are statically mapped at configuration time—if not enough DSPs are left on a NM-HDV, the configuration of the ds0/pri-group will not succeed

    • Each NM-HDV can be configured to participate in DSP Resource Pool or not

    • All NM-HDVs participating in the DSP Resource Pool must be synchronized to the same clock

    • All NM-HDVs that participate in the DSP Resource Pool should be configured with the same codec complexity—DSP assignment is not deterministic if the network modules are of mixed complexities

    • NM-HDVs need not be a PDVM for the DSP Resource Pool functionality to operate

  • EADI (Enhanced Availability D&I) is available for D&I applications across Cisco 3660 backplane. This feature provides for the survival of the TDM cross-connections through a software reload of Cisco 3660.

  • Enhanced Circuit emulation of T1/E1s can now be supported on Cisco 3660 through MIX. Voice channels of T1/E1 on NM-xFE2W and NM-HDV network modules can be transported across the MIX module to ATM OC-3 network modules (NM-1A-OC3XX-1V) over an ATM network.

  • Clocking options—All network modules (NM) that communicate over the MIX module (MIX-3660-64) must be clocked from the same source. The clocking source can be internal or external. Internally, these network modules must derive clock from MIX module (MIX-3660-64). Externally, clock from the PSTN can propagate across MIX-3660-64 to all network modules via a VWIC that's connected to the PSTN. Finally, all NM's communicate over the MIX module must be in the same clock domain.

The Multiservice Interchange (MIX) solution on the Cisco 2600, 3620 and 3640 enables the following key feature:

  • Connection of TDM streams between two Voice/WAN interface cards (VWICs) on the same Fast Ethernet network module (NM-xFE2W, does not apply to the Cisco 2600)

  Participating VWICs are:
  • VWIC-1MFT-T1, VWIC-1MFT-E1

  • VWIC-2MFT-T1, VWIC-2MFT-E1

  • VWIC-2MFT-T1-DI, VWIC-2MFT-E1-DI

  • VWIC-1MFT-G703, VWIC-2MFT-G703

Applications

TDM Voice Switching Solution

In pure D&I applications, Cisco 3660 does not participate in voice processing. It functions purely as a cross-connect for TDM streams from, say, a PBX to the PSTN. For many customers though, this is a viable first step in the integration of voice and data traffic onto a combined infrastructure before taking the leap into VoX technologies.

This type of application can be used to:

  • Aggregate voice traffic from multiple PBXs from different branches or building locations, each connecting through a T1/E1 leased line to a Cisco 3660

  • Aggregate voice traffic to the PSTN from multiple PBXs in a high-rise building or mall (multi-tenant situation)


Figure 2: TDM Voice Switching Application

In Figure 2 above, a sample application is depicted where voice traffic from seven PBXs, each with less than half the channels on the T1/E1 actively used, is consolidated onto two T1/E1 ports to the PSTN, providing substantial cost savings in the number of PSTN trunks required for this traffic. In the example, the solid lines from the PBXs aggregate onto the solid line to the PSTN, and the dotted lines aggregate onto the dotted line to the PSTN.

For purposes of illustration some PBX T1/E1s are connected to a NM-HDV while others are connected to NM-xFE2Ws. The DSPs reside on the NM-HDV are not used in this example. Its benefit would be to ease the next migration step when the customer wants to start using VoX for some voice channels. If all the D&I channels are connected to NM-xFE2Ws, the customer will have to buy at least one NM-HDV when he wants to start deploying VoX (and probably more if DSPs on the NM-HDV has to drive voice channels on both the NM-HDV as well as NM-xFE2W). On the other hand, the benefit of the NM-xFE2W is higher density of T1/E1s (4 vs. 2 for the NM-HDV) per NM slot.

The example also shows how the second port on the ATM OC-3 CES card can be used in the D&I application.

VoX for On-net, TDM D&I for Off-Net Solution

Another common application for cross-NM D&I is to cross-connect the Off-net voice traffic (PBX to PSTN), while using VoX technology for the On-net traffic (PBX to PBX across the enterprise network).

In Figure 3 below, a sample application is depicted where the PSTN voice traffic from four PBXs are consolidated onto a single T1/E1 port to the PSTN, providing substantial cost savings in the number of PSTN trunks required for this traffic. In addition, several channels from some PBXs are On-net traffic and these are using a VoX application. The cross-connected channels to the PSTN will be configured using tdm-groups, while the channels using VoX will be ds0-groups.


Figure 3: VoX for On-net, TDM D&I for Off-Net Solution

The voice channels using VoX must have access to DSPs, so there must be at least one NM-HDV in the 3660. The VoX channels connected to the NM-xFE2W will draw its DSPs from the NM-HDV via the DSP Resource Pool sharing feature discussed in this paper.

The MIX Module Architecture (for Cisco 3660 only)

To enhance its flexibility, integration, versatility and efficiency, Cisco 3660 multiservice platform supports one internal TDM slot and two internal Advanced Integration Module (AIM) slots on its motherboard. The MIX module (MIX-3660-64) plugs into the TDM slot and is designed for Cisco 3660 platform only. The AIM slots are used for compression and encryption AIM modules.

The TDM slot connects to both the Cisco 3660's main system bus and a secondary TDM backplane bus running between the WAN interface card (WIC) slots and network module (NM) slots. This flexible architecture enables the MIX module to integrate different types of traffic, whether it is TDM voice, packet voice or data, on a single T1 or E1 connection, enabling customers to manage traffic through their routers efficiently. By supporting the combination of different types of traffic on Cisco 3660 multiservice platform, MIX helps customers migrate smoothly from TDM voice to packet voice on one integrated platform. In addition, MIX can save customers WAN bandwidth by mixing TDM voice and packet data on the same link using Drop and Insert function.

Integrated V.92 Analog Modem NMs for Cisco 2600, 3660 and 3700

CISCO/라우터 & 라우팅 시스템 2007/05/04 12:25
Cisco Integrated V.92 Modem WAN Interface Cards

One- and two-port analog modem WAN interface cards (WICs; part numbers WIC-1AM-V2 and WIC-2AM-V2) are now available for the award-winning Cisco® 1800, 2600XM, 2691, 2800, 3700, and 3800 Series modular router platforms. The new version of these cards expands the already extensive range of WICs currently available for these routers (Figure 1). The interface cards provide cost-effective basic telephone service connectivity to allow remote router management, asynchronous dial-on-demand routing (DDR) and dial backup, dial- and fax-out modem access, and low-density remote-access-server (RAS) services. Combined with the differentiated services delivered through Cisco IOS® Software, the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 Series routers offer customers
best-of-breed scalability, flexibility, and investment protection-all in cost-effective, multifunctional platforms.

Figure 1. One- and Two-Port Analog Modem WICs for Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 Series Platforms

Both cards feature dual RJ-11 connectors, which are used for basic telephone service connection. The 2-port card uses one port for connection to a standard telephone line and the other port for connection to a basic analog telephone for use when the modem is idle.

KEY BENEFITS

Combined with the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800, the cards provide:

• An integrated solution for ease of deployment and management

• Enhanced remote management capabilities

• A cost-effective alternative to leased lines or ISDN

• On-demand dial backup for critical WAN links

KEY FEATURES

Equipped with the new integrated analog modem WICs, the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 offer the most flexible, scalable, and manageable telephone dial access solution available on the market today.

• Internal analog modem dialup capability-Internal modems allow simple setup of a remote router. There is no separate external power and no cables, and everything is in one chassis.

• Support for speeds up to 56K (V.92 specification)-When dialing out to a digital endpoint, this feature allows users to achieve maximum data transfer rates, equating to faster file transfers, speedier Web access, and faster e-mail downloads.

• Cisco IOS Dial Access Software-Cisco IOS Software provides a broad range of features for remote router management and dial backup, including:

–Reverse Telnet support for LAN-based dial- and fax-out

–Point-to-Point Protocol (PPP), Multilink PPP (MLPPP), and Serial Line Internet Protocol (SLIP)

–TACACS+, RADIUS, and PPP password security

–Autosensing Internetwork Packet Exchange (IPX), Transmission Control Protocol/IP (TCP/IP), AppleTalk Remote Access (ARA), and AppleTalk Control Protocol (ATCP)

APPLICATIONS

Remote Router Management

Figure 2. Remote Router Management

The cards are ideal for dialup access for remote router configuration and management (Figure 2). Similar to connecting a modem to the router auxiliary port, the modem WICs allow out-of-band management through an internal device. Both WICs can receive calls at speeds as fast as 33.6 kbps, depending upon line conditions.

Dial Backup and Asynchronous DDR

Figure 3. Dial Backup and Asynchronous

Constant WAN access is often a requirement for branch offices connecting to a corporate site or the Internet. Although DSL, Frame Relay, ISDN, and leased line are common choices for a primary WAN link, an alternate data path is sometimes needed. The WICs combined with the Cisco 1800, 2600XM, 2691, 2800, 3700, and 3800 offer the ability to automatically dial a backup connection when the primary WAN link is unavailable. In addition, the modem WICs can also be used to provide supplemental bandwidth when the primary WAN link is overused. Multiple modem calls can be aggregated using MLPPP when one 56K connection is insufficient.
For some customers, dialup telephone service connectivity may be the only available choice for WAN access to the Internet or to a corporate home office. For those situations and for those installations that require only a dialup connection, the Cisco routers with the integrated modem WIC offer WAN connectivity through asynchronous DDR. As in the case of dial backup, MLPPP can be used to aggregate multiple dialup connections into one data stream, providing higher throughput.

Dial- and Fax-Out Modem Access

Figure 4. Dial- and Fax-Out Modem Access

The modem WICs comply with RFC 2217 and provide dial- and fax-out modem functions to LAN-connected devices (Figure 4). Using the recommended "Advanced COM Port Redirection" software (available from http://www.tacticalsoftware.com), customers can take advantage of the modem WICs as if they were connected directly to their PC communications port, allowing convenient access to services such as America Online, CompuServe, and remote fax machines without requiring dedicated phone lines and modems at each PC.

Note: The WICs do not have the ability to receive faxes; only fax-out is supported.

Low-Density Analog RAS Access

Figure 5. Low-Density Analog RAS Access

Dial-in users can take advantage of the ability of the router to function as a small RAS, thus allowing dialup access to the LAN (Figure 5). Typically, a 2-port modem WIC would be used here for maximum port density, but the 1-port WIC is also acceptable. Scalability to multiple modem WICs per chassis (up to 12 in a Cisco 3845-refer to Table 3) is also possible. Dial-in speeds of up to 33.6 kbps (V.34bis) are possible. MLPPP is available to bond two or more calls together, thereby allowing higher-speed RAS support.
