9. To ensure that the synchronization integrity of the networkboth this com-
munications system and its far-end connections
is protected, prepare the
Network Planning Map on page 4 for review by NTM. Describe the entire
network of DS1 facilities by summarizing the following for each 100D mod-
ule:
a. Fill in the control unit slot number(s) of the 100D modules connected to
the CSU(s).
b. Write the approximate number of cable feet between each module and
its CSU or far-end connection (refer to the Line Compensation entry on
Form 3b, Page 1).
c. For the model number(s) of the CSU(s), do
one
of the following:
■
If the CSU is the ACCULINK 3150, check the box for the ACCULINK
3150.
■
If the CSU is not the ACCULINK 3150, check the Other box and write
the manufacturer’s name and model number in the space provided at
the bottom of the page.
■
If no CSU is needed, check None.
d. In the connection block(s), describe the DS1’s far-end connection by do-
ing
one
of the following:
■
If connected to the telephone company central office, check CO.
■
If connected to another communications system, check PBX.
■
If connected to the PRI network, check PRI.
■
If the facility’s type of service is T1, check the type(s) of emulated
trunks. Also, check the Services box if the facility includes services
such as MultiQuest with DNIS.
e. Describe the clock synchronization sources according to the key at the
lower left of the map.
i. Draw a circle and line from the clock source to the appropriate 100D
module.
ii. Label the circle
P for primary, S for secondary, or T for tertiary.
10. Make a copy of the T1/PRI Planner for your records and forward the original
to NTM.
As an example, the system described in Figure D-1
shows a processor module
system with two 100D modules.
