3 Lines/Trunks
Identifying Line/Trunk Jacks
This procedure also includes instructions for assigning a label to identify the line/
trunk being used.
Planning Form Instructions
1. In the Incoming Line/Trunk Type column of Form 2c, write the type of line/
trunk you plan to connect to each line/trunk jack, T1 channel or BRI
channel: Main No., personal line, FX (Foreign Exchange), WATS (include
band), DID, or Tie. (Contact the local telephone company for line/trunk
information.) Use the following guidelines:
2. If the jack type shown in the Jack Type column is GS/LS, then write either
GS or LS to indicate the line/trunk type in the Incoming Line/Trunk Type
column. For a T1 or NI-1 BRI trunk not used at this time, write unequipped.
For other T1 or PRI facilities, the kind of service connected (such as
Megacom 800) will be filled in later.
3. In the Telephone Number or Equipment column, write the telephone
number for each incoming line/trunk (as supplied by the local telephone
company) on the row with the logical ID for its line/trunk jack. If you do not
know the telephone number, leave the column blank and enter the
information later.
Group trunks together according to type: basic loop-start or ground-
start trunks, and special-purpose loop-start or ground-start trunks.
(DID, PRI, T1, BRI and tie trunks are automatically grouped
according to type since they require specific types of modules.) The
local telephone company supplies the information you need to
identify the specific trunks connected to each line/trunk jack on each
DID and tie trunk module and each channel on each 100D or 800
NI-BRI module.
Use line/trunk jacks at the beginning of the sequence for basic
ground-start and/or basic loop-start trunks. Use jacks later in the
sequence for special-purpose trunks such as WATS or FX.
If a line/trunk such as WATS is only inbound or only outbound (not
two-way), include that information along with the line/trunk type.
NOTE:
In the next step, be sure the line/trunk type associated with each
telephone number matches the jack type. Also, if you have 800 NI-
BRI modules or have dedicated 100D module channels to emulate
loop-start, ground-start, and/or tie trunks, the local telephone
company will supply the telephone number associated with each of
the channels on the BRI or DS1 facility.
