Introduction
This document provides configuration information for how to connect two BPX 8600 switches with
narrowband trunks. Each BPX 8600 switch has an MGX 8220 Edge Concentrator connected as a feeder shelf.
The customer premises equipment (CPE) is connected to the feeder shelf. A four T1 inverse multiplexing over
ATM (IMA) trunk group is established between two MGX 8220 IMATM−8T3T1/B service modules. A T3
trunk is established between each BPX 8600 BXM−T3 service module and the respective MGX8220
IMATM−8T3T1/B. Two Cisco multichannel (MC) 3810 routers with Frame Relay interfaces are connected to
each of the MGX 8220 Frame Relay Service Modules (FRSM)−8T1. IP connectivity between two Cisco MC
3810 routers is achieved through a network interworking (NIW) connection. The MGX 8220 FRSM−8T1
service modules provide the NIW conversion. BPX 8600 switches provide the switching function for this
connection.
