The T1/E1 High Density Cross Connect LIM is a 28 or 32-port LIM intended for use
with the PCx-2 slot controller for aggregation of T1, E1, OC-3, OC-12, E3 and DS3
circuits across a packet network. It supports the following rates:
•
T1 data rates up to 1.544 Mbps
•
E1 data rates up to 2.048 Mbps
•
DS3 data rates up to 44.736 Mbps
•

Front Panel Features
The front panel connectors provide easy access to the ports. The front panel LEDs
indicate LIM communication status. All LEDs are controlled by the slot controller
software:

Hardware Setup
Jumpers
Jumpers on the T1/E1 HDCC LIM are for factory use only.
Installation
The T1/E1 HDCC LIM occupies a rear panel slot of the switch that is associated with
the corresponding controller. When handling LIMs, always use an antistatic wrist
strap to prevent static discharge damage to the electronic circuits.
1. Install the LIM into an empty slot at the back panel of the chassis.
2. Insert the edges of the module into the tracks of the slot and slide the module
inward until it stops. (LIMs are "hot-swappable".)
3. Connect the appropriate I/O line(s) to the LIM's front panel input connectors
using the proper cables.
4. Refer to the Xedge Configuration Guide to properly configure the LIM for your
application.
