Digital J1 Packet Voice
Network Module
The Digital J1 Packet Voice Network Module provides a flexible and scalable J1 voice and fax solution for the Cisco 2600, 2600XM, 3600 and 3700 series multiservice Modular Access routers and supports up to 30 voice channels in a single network module. A single packet voice network module supports connections to Japanese Private Branch Exchanges (PBXs), and is compliant with the J1 TTC JJ20 standard. The network module eliminates the need to use expensive external third-party T1 to J1 converter products. This network module is ideal for enterprise branches, large businesses and service providers wishing to migrate to packet-based multiservice infrastructures. It also enables the deployment of new packet voice applications while reducing recurring telephony charges.

The Digital J1 Packet Voice Network Module uses a real-time CPU and 12-channel packet voice digital signal processing (DSP) modules (PVDM-12) which support all functions needed to provide the highest levels of voice fidelity and quality, reducing the processing burden from the Cisco 2600, 3600 or 3700's main CPU. The packet voice network module includes a VIC-1J1 voice interface card which offers a single port J1 voice/fax interface.
Now, enterprise offices of several hundred users and managed network service providers can deploy multiservice networking using a single box solution.
Key Features and Benefits
- Interface to Japanese PBXs to route voice and fax, eliminating the need for an expensive external third-party T1 to J1 converter product.
- Programmable digital signal processors can support both medium- (G.729A, G.729B, G.711a- and u-law, G.726 all versions, clear-channel, fax-relay) and high-complexity CODECs (G.728, G.729, G.729B, G.723 all versions, GMS, GSMEFR, modem relay) for customized solutions to meet the need for high voice quality and bandwidth efficiency
- Packet Voice Digital Signal Processor Modules (PVDM-12=) provide the ability to increase the voice processing capabilities within a single network module
- Support of additional modular voice processing requirements on the Cisco 2600, 3600 and 3700 platforms such as routing, dial concentration, firewall, encryption and VPN.
Feature Summary
Table 1 Digital J1 Packet Voice Network Module Feature Summary
| Feature | Benefits |
|---|---|
| J1 Standards Support |
Supports the TTC JJ-20.10-12 standard with a line rate of 2.048 Mbps |
| Scalable from 1 to 30 Voice Channels |
Single Network Module scales using from one to five 12-channel packet voice DSP module (PVDM-12) upgrade SIMMs to support from 1 to 30 voice channels. |
| Standards-Based PCM Encoding |
Standards-based ITU-T G.711 PCM encoding provides 64 kbps analog to digital conversion using u-law or A-law. |
| Standards-based Compression Algorithm Support |
Users can choose to either transmit voice across their networks as uncompressed PCM (G.711, u-law and A-law) or compressed from 5.3 kbps to 32 kbps using standards-based compression algorithms (G.729, G.729a/b, G.723.1, G.726, G.728). |
| Fax Support |
Transmit Group III fax and T.38 over any voice channel without sacrificing voice processing resources regardless of compression type. |
| Voice over IP |
Transmit voice across a single frame relay, ATM, ISDN, channelized, or multilink point-to-point protocol (MLPPP) network. |
| Voice over Frame Relay |
Leverage existing or new frame relay network by transporting voice directly over this network using standards based transport methods (FRF.11). VoIP can also be transmitted over Frame Relay. |
| Voice over ATM |
Transport voice directly over ATM networks using AAL 5 encapsulation. Leverages existing ATM networks as a direct transport method for voice. VoIP can also be transported over ATM (VoATM requires ATM network modules such as IMA or OC-3). |
| Connection Trunk |
Creates a tie-line replacement structure while only consuming bandwidth during a call. |
| Toll Bypass |
Reduce or eliminate toll charges assessed by long distance and local carriers by transporting voice and fax traffic across the enterprise intranet, LAN, metropolitan-area network (MAN), or WAN. Businesses incur significant recurring monthly costs for leased lines purely for the interconnection of telecom PBXs and switches. This product gives these enterprises the ability to remove these costly rigid-bandwidth leased lines and replace them with flexible bandwidth lines. The ability to support proprietary PBX signaling types exists by using connection trunking and transparent CCS. |
| LVBO (Local Voice Busy-Out) and AVBO (Advanced Voice Busy-Out) |
Automatically busy out any desired voice trunk line (or individual DS0s) to a PBX when a direct WAN or LAN connection to the router is down. Also, busy out a far end trunk connection when configured for Connection Trunk. AVBO adds the capability to busy out voice trunk lines triggered by Security Assurance Agent (SAA) probes. |
| Local and Remote Loopback |
Supports three types of loopback modes - line and local loopback, and isolation. |
| T-CCS (Transparent Common Channel Signal) |
Supports clear channel transparent common channel signaling |
| J1 CAS (TTC JJ-20.10-12) |
Supports J1 channel associated signaling |
| H.323 Support |
Uses industry-standard signaling protocols for call setup between gateways, gatekeepers, and H.323 end points. Enables comprehensive, flexible application configuration for voice over IP, desktop video conferencing, collaborative computing and electronic whiteboard applications. |
| DTMF Relay |
Carries DTMF tones/information out-of-band for clearer transmission and detection. |
| Any Call to Any Call with end-to-end Interoperability |
Interoperates with Cisco IP phones, analog phones, fax machine connections, and PBX connections to and from any other Cisco voice enabled product. |
| AVVID IP Telephony Interoperable |
Interoperable within Cisco's AVVID IP Telephony architecture (H.323 Networks) |
| VoIP Call Control Signaling |
Supports H.323 call control protocols. |
| Gateway for IP phones, fax machines and key communication systems to Japanese PBXs |
Enables a connection for incoming and outgoing calls to Japanese PBXs using Cisco IP phones, fax machines and other key communnication systems connected to a data, voice and video infrastructure |
