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.

- Weird serial interface problem. And I applied it inbound on the serial interface. Hardware is DSXPNM Serial.
The real problem here is that the second router’s serial interface is not on the same IP subnet as router #1. Even though they have the same subnet, the 10.2.100.5 IP address will never be able to communicate to the 10.2.100.2 IP address because they are on different networks but directly connected.
The 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 NetFlow. The Cisco 3945E, for instance, is the highest-performing platform for the branch office and is recommended for deploying concurrent services at full T3/E3 line rates. See Table 1 below for performance recommendation for positioning of the NM-1T3/E3 in the branch office. Cisco T3/E3 Network Module Branch Office Positioning and Platform Support Matrix.
