One-port clear-channel T3/E3 network module


NM-1T3/E3

The Cisco® T3/E3 Network Module provides high-speed WAN access for the Cisco 2600, 2800, 3600, 3700 , 3800 Series routers, as well as the Cisco 2951, and 3900 Series Integrated Services Routers. The NM-1T3/E3 network module offers both Service Providers and Enterprise customer's unprecedented flexibility in provisioning clear-channel T3 or E3 connections.

Cisco's Packet-over-T3/E3 network module for the Cisco Integrated Services Routers series offers the first software-configurable T3/E3 product from Cisco. This flexible network module allows the customer to switch between T3 and E3 applications with a single Cisco IOS® command. This feature provides customers increased flexibility and investment protection by allowing a Cisco Partner, service provider or enterprise customer to stock only a single product that can be deployed internationally.

The increased demand for bandwidth over the WAN and more attractive pricing of T3/E3 links by SPs has led to steady growth in T3/E3 deployments around the world. The Packet-over T3/E3 network module (part number NM-1T3/E3) eliminates the need for an external data service unit (DSU), reduces provisioning costs, and provides highly manageable T3/E3 line termination. The module provides an integrated line interface unit (LIU) DSU that allows T3 or E3 lines to be directly terminated on a Cisco router, eliminating the need for external DSU equipment. This simplifies the T3/E3 line management, reduces provisioning cost, and frees up valuable rack space.

The Cisco T3/E3 network modules provide support for the proprietary subrate and scrambling features of T3 DSU vendors such as Digital Link, Larscom, and ADC Kentrox. Subrate support in the Cisco T3/E3 Network Module maximizes the utility of these products in service provider environments By simultaneously supporting interoperability with a wide range of third-party DSU vendors, this network module offers the flexibility to support installed equipment without locking customers into a proprietary solution.

The Cisco T3/E3 Network Module provides direct connectivity to a T3 line for full-duplex communications at the T3 rate of 44.736 MHz and full-duplex E3 communications at 34.368 MHz. Each T3 or E3 port consists of a pair of 75-ohm BNC coaxial connectors (Type RG-59), one for transmit data and one for receive data, along with six LED indicators for line status. The Cisco T3/E3 Network Module is supported in all Cisco IOS feature sets, and there are no additional memory requirements.
