Cisco SM-X-1T3/E3 Packet-over-T3/E3 Service Module for Cisco Integrated Services Routers

43,057.00 SR

Enable your Cisco integrated service router to quickly switch between T3 and E3 WAN modes with the SM-X-1T3/E3 Packet-over-T3/E3 Service Module for Cisco Integrated Services Routers from Cisco. Designed for use with Cisco 2900, 3900, and 4000 Series integrated service routers, the SM-X-1T3/E3 service module lets you switch between T3 and E3 applications by executing a single Cisco IOS Software command.

This one-port service module comes equipped with two 75 Ohm BNC coaxial connectors, one for transmitting and another for receiving. Full-duplex T3 and E3 communication is supported. An integrated line interface unit (LIU) allows T3 or E3 lines to be directly terminated on your compatible Cisco router.

T3/E3 Line Termination
The increased demand for bandwidth over the WAN and more attractive pricing of T3/E3 links by service providers has led to steady growth in T3/E3 deployments around the world. The T3/E3 module 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, simplifying the T3/E3 line management, reducing provisioning cost, and freeing valuable rack space.
Interoperability with Third-Party DSU Vendors
The T3/E3 module supports the proprietary subrate and scrambling features of T3 DSU vendors such as Digital Link, Larscom, and ADC Kentrox. Subrate support in the module helps to maximize the utility of these products in service provider environments. By simultaneously supporting interoperability with a wide range of third-party DSU vendors, this module offers the flexibility to support installed equipment without locking customers into a proprietary solution.
Compatibility
The Cisco T3/E3 Service 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 transmitting data and one for receiving data, along with six LED indicators for line status. The T3/E3 module is supported in most Cisco IOS Software feature sets, and there are no additional memory requirements.
