Figure 1. Digital T1/E1 Packet Voice Trunk Network Module (NM-HDV-2E1-60 Pictured)

The Digital T1/E1 Packet Voice Trunk Network Module provides a flexible and scalable T1/E1 voice solution for Cisco 2600, 2600XM, 2811, 2821, 2851, 2691 3600, 3700 series and 3800 series multiservice Modular Access routers and supports up to 60 voice channels in a single network module. A single packet voice trunk network module supports both on-premise and off-premise connections to both Private Branch Exchanges (PBXs) and Public Switched Telephone Networks (PSTNs). These products are ideal for enterprise branches, large businesses and service providers wishing to migrate to packet-based multiservice infrastructures. This network module leverages existing legacy telephony equipment investments in addition to providing the ideal gateway interface for IP telephony within the Cisco Architecture for Voice, Video and Integrated Data (AVVID). It also enables the deployment of new packet voice applications while reducing recurring telephony charges.
The Digital T1/E1 Packet Voice Trunk Network Module uses a real-time cpu and powerful digital signal processors (DSPs) which support all functions needed to provide the highest levels of voice fidelity and quality, eliminating the processing burden from the Cisco 2600/2600XM/2691/2800/3600/3700/3800 main CPU. These DSPs can be scaled to support from six to 60 voice channels in a single Network Module using a number of different voice compression algorithms. The packet voice trunk network modules include a MultiFlex Voice/WAN interface card (VWIC) which offer single and dual port T1 or E1 interfaces for additional versatility and scalability. This flexibility allows voice and fax traffic to travel cost-efficiently across a user's wide area network (WAN) or directly over the PSTN.
The Digital T1/E1 Packet Voice Trunk network module combined with the Cisco 2600/2600XM/2691/2800/3600/3700/3800 series multiservice access routers make an ideal single-box solution for packetized voice in branches and regional offices. Up to six packet voice trunk network modules can be configured in a single modular access router, supporting from 6 to 300 voice channels. Now, enterprise offices of several hundred users can deploy multiservice networking using a single box solution. Service providers, providing data and telephony managed services can connect a single platform to their central offices or points of presence (POPs) with a single high-speed data connection. The packet voice trunk network modules seamlessly interoperate with smaller and larger multiservice platforms from Cisco.
The Digital T1/E1 Packet Voice Trunk Network Module provides an ideal migration path to a multiservice network. Customers can gradually shift voice traffic from traditional circuit-switched networks to a single infrastructure carrying data, voice and video over packet networks without replacing any legacy PBX and key communication system equipment. This network module also provides the perfect solution for PBX and PSTN access to IP telephony in the Cisco AVVID architecture.
With connectivity support for over 90% of the world's medium and large traditional circuit-switched PBXs and PSTNs, the Digital T1/E1 Packet Voice Trunk Network Module provides every Enterprise the ability to integrate voice and data into a single multiservice infrastructure. As a result Multinational Enterprises can be prepared to implement new integrated applications immediately.
The Digital T1/E1 Packet Voice Trunk Network Module provides:

• The gateway interface to PBXs to route voice along with data and video over a single data infrastructure

• The gateway to the PSTN allowing users to gain access to the public telephone network to and from traditional PBX, phone, fax, key communication systems, as well as IP telephony as an integral part of the Cisco AVVID architecture

Feature Summary

Table 1. Digital T1/E1 Packet Voice Trunk Network Module Feature Summary

Feature

Benefits

Scalable from 6 to 60 Voice Channels

Single Network Module scales using from one to five 12-channel packet voice DSP modules (PVDM-12) upgrade SIMMs to support from 6 to 60 voice channels.

Platform Voice Scalability to 300 Voice Channels

Enables Cisco 2600, 2600XM, 2691, 2800, 3600, 3700, 3800 series modular access routers to scale from 6 to 300 voice channels in a single multiservice router solution.

Network Module

Enterprises and service providers can use a single box to support data and telephony services by sharing this Network Module with other interfaces in the Cisco 2600, 2600XM, 2691, 2800, 3600, 3700, 3800 series modular access routers.

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 over any voice channel without sacrificing voice processing resources regardless of compression type.

Voice Over IP

Transmit data, voice, and video 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) combined with standards based fragmentation for data (FRF.12). VoIP can also be transmitted over Frame Relay.

Voice Over ATM

Transport voice directly over ATM networks using AAL2 and 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 (digital-to-digital, digital-to-analog, or analog-to-analog capabilities).

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.

Integrated Data WAN Support

Connect one or two T1 or E1 interfaces on this network module as a WAN interface either as one or multiple groups of DS0's or as an entire T1 or E1 frame while still providing packet voice support for connections to PBXs and the PSTN.

LVBO (Local Voice Busy-Out)

Automatically busy out any desired voice trunk line (or individual DS0s) to a PBX or PSTN 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.

Call Admission Control Using RTR

Uses Response Time Reporter (RTR) to determine latency, delay and jitter and provide real-time ICPIF calculations before establishing a call across an IP infrastructure. RTR packets emulate voice packets receiving the same priority as voice throughout the entire network. A superior method to data and ping packets for determining congestion levels.

Off-Premise Extension (OPX)

Extends the capability of legacy PBX to off-premise phones.

Voice Activity Detection (VAD)

Consume bandwidth during a call only when there is voice traffic to send (silence suppression)

Comfort Noise Generation

While using VAD, the DSP at the destination emulates background noise from the source side, preventing the perception that a call is disconnected.

Circuit Switched Leased Line Replacement

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, which will be used to carry data, voice, and video. The ability to support proprietary PBX signaling types exists by using connection trunking and transparent CCS.

Private Line Automatic Ringdown (PLAR)

Provides a direct connection to another digital or analog voice port by lifting a telephone handset on one end.

H.323 Version 3 and 4 Support

Uses industry-standard signaling protocols for call setup between gateways, gatekeepers, and H.323 end points (such as Intel Internet Phone or Microsoft Netmeeting).

DTMF Relay

Carries DTMF tones/information out-of-band for clearer transmission and detection.

Authentication, Authorization, and Accounting (AAA)

Supports debit and credit card (prepaid and post-paid calling card) applications.

Interactive Voice Response Support (IVR)

Utilizes IVR to provide automated-attendant, voice-mail support, and call routing based on desired service.

Open Settlement Protocol Support (OSP)

Provides the ability to settle account billing between service providers who are sharing resources to expand geographical coverage using third-party tools and standards-based OSP.

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.

Gateway for Legacy PBXs, Phones, Fax Machines, and Key Communication Systems to PSTN

Enables a connection for incoming and outgoing calls to and from the PSTN originating from and destined for legacy PBXs, phones, fax machines, and key communication systems connected to a data, voice, and video infrastructure.

Integrated Add/Drop Multiplexer

Performs add/drop multiplexing for voice within a dual-port voice Network Module. Eliminates the requirement, maintenance, support, and expense found when using an external add/drop multiplexer.

AVVID Interoperable

Interoperable within Cisco's AVVID architecture.

Call Control Signaling

Supports H.323 v3/v4, MGCP, and SIP call control protocols.

Gateway for IP phones to PSTN or Classic PBXs
