Issue 1.0, April 2006 Section 364-180-N02

2. General Overview

This document supports both the 3641-80 Single Port router and the 3648-80 router which

includes an 8 port Ethernet switch. The router cards are Ethernet IP routers, which mounts in a

full size card slot. The only difference between the 3641-80 and 3648-80 is that the 3648-80 has

an unmanaged Ethernet switch to eliminate the need for an external switch. Therefore the routers

will be referred to as ‘the router’. The router includes an Ethernet interface to provide data

services from the T1/E1 interface. The router can act as a frame relay router, frame relay bridge,

firewall, VPN gateway, or IP sharing.

For purposes of understanding, the Ethernet port represents the LAN side of the router and the

T1/E1 represents the WAN side of the router.

The router card provides three primary services:

1. Provides a standard T1/E1 gateway function between the customer Ethernet interface and

the WAN data service channel on the T1/E1 interface.

2. Provides the possibility for including voice and data over the same T1/E1 line.

3. Provides a flexible programmable data rate 56/64K x N bps where N = 1…24 for T1, 1…30

for E1 (i.e. 56K ~ 1.536M bps for T1, 56K ~ 1.92M bps for E1).
