Connect DLT

Digital (also referred to as Logical) Loop Test (DLT) access is gained by wiring into the P23 
connector, labeled 

DSX-1/E1 TEST ACCESS

, on the right side of the backplane. To wire the Total 

Access 3000 Chassis for DLT access, perform the following steps:

1. After locating the test loops and running them to the Total Access 3000 Chassis, use wire 

strippers to strip approximately 1 to 1-1/2 inches from the test leads.

2. Using the wire-wrap tool, wire wrap the central office “T” and “R” leads to the Total Access 

3000 Chassis “R” and “T” pins, respectively, on terminal P23.

3. Wire wrap the drain wire of the cable to the top pin labeled “S” on P23. If the drain wire 

has been grounded at the test head, do not connect it to the “S” pin. Only one should be 
grounded.

4. Wire wrap the central office “T1” and “R1” leads to the Total Access 3000 Chassis “R1” and 

“T1” pins, respectively, on terminal P23.

5. Wire wrap the drain wire of the cable to the bottom pin labeled 

S

 on P23. If the drain wire 

has been grounded at the test head, do not connect it to the 

S

 pin. Only one should be 

grounded.

6. Neatly tie down the test cable pair.

Figure 8

 is an illustration of connecting DLT to the Total Access 3000 Chassis.

Wiring to DSX-1

The Total Access 3000 Chassis receives its DSX-1 feed from the DSX cross-connect panel in 
the CO. For HDSL, ISDN and T1 deployment, the Total Access 3000 Chassis accepts 28 
DSX-1s from the CO via two 64-pin amphenol connectors to the backplane on Pairs 7 and 8. 
For full deployment of Optical DS2, 4 DSX-1s are needed on each slot, and are received on 
four 64-pin amphenol connectors on Pairs 5, 6, 7, and 8. The female amphenol connectors 
plug into the rear of the Total Access 3000 chassis on the appropriate male Pair connectors.
Refer to the Installation and Maintenance Practices for the access modules being deployed, for 
a full description of the different Total Access 3000 loop assignments and pinouts.
