Your Source for New or Used Cisco NM-1T3/E3=
Cisco 3600 Series  Cisco 3600 Series Modules NM-1T3/E3= One port T3/E3 network module
The Cisco® T3/E3 Network Module provides high-speed WAN access for the Cisco
2600, 3600, and 3700 series Multiservice Access routers and well as the Cisco
2800 and 3800 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 2600, 2691, 2800, 3600,
3700 and 3800 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 SP's 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.
KEY BENEFITS
The combination of T3 and E3 options in a single network module provides the
following key customer benefits:
- Physical space savings-Eliminates the need for external DSU device, saving
valuable rack space
- Simplified management-Eliminates the need for two separate monitoring
tools
- Software-configurable T3/E3-Provides the flexibility to deploy a single
module worldwide
KEY FEATURES
- One-port T3 with DSU or E3 with DSU network module

T3/E3 APPLICATIONS AND POSITIONINGThe Cisco T3/E3 Network Module
provides the performance requirements to deploy advanced, voice, video and data
applications over the WAN and supports key IOS features and services such as
QoS, NBAR, IPSec, FW, IDS, NAT and NeFlow. The Cisco 3845, for instance, is the
highest-performing platform for the branch office and is recommended for
deploying concurrent services at T3 line rate's. See table 1 below for
performance recommendation for positioning of the NM-1T3/E3 in the branch
office.
