he following is a step-by-step procedure for turning up the shelf
after it has been mounted in the equipment bay, all wiring has
been made, and all switches and straps have been set.
NOTE: All switches have been set at the factory for the default setting.
The only changes to the switch settings are the setting of the
E-System Adapter address, the configuration of alarm point
level indicators, if they are required, and the setting of the MAP
memory (switch 5 position 7 to ON) after configuration is
complete.

(See DJ05725 for simple block drawing and how to connect cables)
1.
Install all modules in the shelf starting with Slot 1 through slot 11.
Refer to the B18-05725-XX Block and Level Drawing page 3 for Mod-
ule slot assignments.
2.
Make power and ground connections to the B18-05725 shelf using
barrier strip B1 for the A battery feed and barrier strip B2 for the
B battery feed, if redundant battery is provided. Ground is connected
to barrier strip terminal B3.
3.
Use the DJ05725 drawing sheets 2 and 3 as references, and connect
the 929-00062-00 DB 15 M/M cables between C1 and C2 and the fiber
optic terminals.
4.
Mount the A25-00710-00 frame block on a frame or use the
A25-00508-01 23" Block mounting bar to mount the cross connect
block on, and mount the mounting bar in the relay rack where the
cross connects will take place.
5.
Connect the four 50 pin connector cables, A26-49029-25, between the
A25-00710-00 cross connect block and the B18-05725 assembly. C1,
C2, C3 and C4 of the B18-05725 assembly and A, B, C, and D of the
cross connect block.

The levels that are used by the modem are -29 dBm XMT and
-6 dBm RCV. This should always apply since all shelves will be
equipped with the Tellabs 4003C card.
The data levels at the 46105 will be -29 dBm XMT (into the 46105)
and -6 dBm RCV (out of the 46105). Refer to Fig 16.
The over-all system levels can be verified by injecting a terminated
-16 dBm, 1 kHz test tone at the far end 46105 XMT drop jack and
measuring the local 46105 RCV drop jack at +7dBM, terminated.
If the signal is not 1 dB of the required RCV test tone
