Installing the Central Office Terminal Equipment
Follow the steps in Table 12 in the presented order to install PG-Flex central office terminal
equipment.
These installation procedures are recommendations. Local practices, if conflicting, should take
precedence. PairGain practices, where indicated, provide detailed instructions for completing
these steps. These should be followed but the sequence may be altered where local needs dictate.
The following procedures are for the 23" COT shelf. For information not covered in this
document, refer to the applicable PairGain technical practice.

1
Local policy determines the sequence of terminal
installation and size capacity of the shelf.
2
Do NOT fuse the power source at this time. Use
local grounding plan.
3
Use local practices to resolve HDSL trouble.
4
Local policy determines testing strategy, so this is an
optional step.
5
Local policy indicates termination points for alarm
leads.
6
This is required only when ISDN channel units are
installed. A building integrated timing supply
(BITS) or equivalent clock source is recommended.
7
“Connect the Subscriber Lines”
Local policy indicates distribution points and
protection steps to be taken.
8
Local policy indicates distribution points and
protection steps to be taken (> 200 Vdc is present on
the power pairs).

fuse should not operate.
10
Check for appropriate battery and ground voltages.

“Install the Alarm Unit or the PGTC” page 50
Either an Alarm Unit or PGTC Interface Unit
can be used but not both.
This is not required for service provisioning. Local
policy determines the appropriate alarm reporting and
line testing strategy. Only one alarm unit or PGTC is
required per COT shelf (supports up to 4 systems).
