Planning Form Instructions 3
1. To assign B-channels to groups, determine which channels to group
together and then record each group on Form 3b (page 3), under the
B-Channel Groups heading:
a. Write the group number (1−80) under the B-Channel Group No.
heading (start with 1 and number sequentially).
b. Write the slot and port number of each B-channel assigned to the
group (see Form 2c, System Numbering: Line/Trunk Jacks). To
determine the port number, assume that port 1 is at the bottom of
the module to which you are assigning B-channels.
c. For all channels you plan to associate with the group, write the trunk
number (see Form 2c, System Numbering: Line/Trunk Jacks).
2. To assign service to each B-channel group, complete Form 3b (page 4) as
follows: If there is more than one 100D module set up for PRI service or
you have more than eight B-channel groups assigned to a module, make
copies of Form 3b (page 4) as necessary.
a. In the Module Slot No. space, write the number of the control unit
slot that contains the module as noted on pages 1 and 2 of this form.
b. Under the B-Channel Group No. heading, copy the B-Channel
group numbers from Form 3b (page 3).
c. Write the services to be associated with each group under the
Outgoing Services and Incoming Services headings. Select from the
following services:
■ AT&T Toll. (for 4ESS or 5ESS, see Form 3b, page 1)
Megacom WATS, Megacom 800, ACCUNET SDS, Software
Defined Network (SDN), MultiQuest, and Long Distance.
■ 5ESS Local. (For switch type 5ESS, see Form 3b, page 1)
OUTWATS, 56/64 Digital, Virtual Private Network, and
INWATS.
■ MCI Toll. (for DMS-250 or DEX600E, see Form 3b, page 1)
MCI Prism, MCI VNet, MCI 800 and MCI 900.
■ DMS-100 Local. (for a DMS-100, see Form 3b, page 1) DMS
Private Network, DMS INWATS (Inward Wide Area Tele-
phone Service), DMS OUTWATS (Outward Wide Area Tele-
phone Service), DMS FX (Foreign Exchange), DMS Tie
Trunk.
■ Other. Call-by-Call, Other.
NOTE:
If a B-channel group has more than one outgoing service,
then enter Call-by-Call on Form 3b, page 4, under the
Outgoing column instead of itemizing the services. Form 3b,
page 8, is where you enter specific services with specific
dial-out patterns.
