DS1 cable installation

Description

This section describes how to connect the DS1 transmission cables to the shelf, route the

cables out of the bay and connect the cables to the DSX. Perform this procedure if DS1

cables are required.

Note:

the DSX becomes an extension of the Alcatel-Lucent 1665 DMX High-Capacity shelf

backplane connections. Thus the IN on the Alcatel-Lucent 1665 DMX High-Capacity

shelf backplane connects to the IN of the DSX and the OUT of the Alcatel-Lucent

1665 DMX High-Capacity shelf backplane connects to the OUT of the DSX

respectively.

The cables are connectorized at the Alcatel-Lucent 1665 DMX High-Capacity shelf end

and must be wire-wrapped at the DSX end. A total of four function groups fully cabled

may have up to 224 DS1 drop capacity if the higher density DS1 circuit packs are

equipped.

Note:

frame ground through the backplane. Alcatel-Lucent recommends that the shield at

both ends of the cable be grounded. Ground at the DSX end per office requirements.

Procedure

Proceed as follows:

Refer to the engineering job specification. Obtain the DS1 cables per

cable assemblies" (p. 1-37)

Label the cables, indicating bay, shelf, function group (A, B, C or D) and direction (IN or

OUT of the bay) at each end.

Note:

connectors (J1- J8). The additional capacity (28 additional DS1s, 29-56) of the

Function Group use the connectors located in the middle of the backplane (J20 - J27).

Connect the function group cables at the Alcatel-Lucent 1665 DMX High-Capacity shelf

end, carefully matching the correct connector with the appropriate backplane connectors

as shown in

Note:

not overtighten.

When cabling the Alcatel-Lucent 1665 DMX High-Capacity shelf to a DSX,

The connectorized cable end is grounded to the Alcatel-Lucent 1665 DMX

and note the function group where each cable will be used.

The first 28 DS1s of a Function Group, must be connected to the bottom
