1.

Identify the two network elements you wish to cross-connect.

2.

Plan placement of the two repeater modules in relay racks, ensur-
ing:

◊

the distance between the network element and the repeater is 
correct for the system, cables in use and office procedures.  
This can be up to 450 feet.

◊

the two repeater modules will not be more than 900 feet apart.

3.

While wearing a grounding strap, remove the repeaters from their 
anti-static bags, touching the module edges only.

4.

Set the jumpers on each module for the appropriate data rate, as 
shown below (factory setting is T3).

5.

Set the jumpers for the transmit and receive distances, as shown 
below (factory settings are Low and Short). See the tables on the 
next page to determine the settings appropriate for the type of ca-
ble being used.
