Introduction
INTRODUCTION
Drop and insert DS3 networking is practical and efficient with the MX3216 system (see Figure
1-1). The MX3216 system routes DS1s between the two DS3 interfaces with access to 22 DS1s
at any node.
The MX3216 interfaces to two coaxial DS3s and provides the ability to drop and insert up to
22 DS1 signals from either DS3 interface on the terminal side. Sixteen of the DS1s are acces-
sible through the amphenol connectors on the back of the MX3 chassis as short haul DSX-1
signals. Six DS1s can be routed to the two expansion slots to allow custom system configu-
ration at each node of the network.
Use an MX3 Remote Management Module (MX3RMM) to add an optional IP router for Ethernet
network extension throughout the network and Telnet-based terminal server ports. When
using a MX3RMM, up to two DS1 interfaces can be dropped from the controller and used in
T1 or FT1 mode. The MX3RMM provides the ability to remotely manage the MX3216 system
using a 10Base-T/100Base-TX Ethernet interface.
