Planning Form Instructions
On Form 3b (page 1), Incoming Trunks: DS1 Connectivity (100D Module), for
each 100D module with PRI service:
1. In the module Slot No. space, write the number of the control unit slot that
contains the module (see the Control Unit Diagram on Form 1).
2. Under the Type of Service heading, check PRI. (During programming, PRI
must be selected here before the PRI options information is entered. When
it is selected, the system restarts.)
3. Under the Switch Type (PRI Service Only) heading, check the PRI switch
type. If the switch is part of a private network, check either Legend-PBX or
Legend-NTWK.
4. Under the Frame Format heading, change the factory setting by checking
the Extended Superframe (ESF) box.
5. Under the Suppression (Line Code) heading, change the factory setting by
checking the B8ZS box.
6. Under the Signaling Mode heading, check Common-Channel Signaling
(CCS).
NOTE:
If more than one 100D module is used, complete the first box,
Module 1, to show the options assigned to the 100D module in the
lowest-numbered control unit slot. Use the second box for the
second lowest-numbered slot and the last box for the
highest-numbered slot.
NOTE:
If the switch is part of a private network and is connected to a
DEFINITY switch, select Legend-PBX. If the switch is connected to
another MERLIN LEGEND system, one switch must be configured
as Legend-PBX and the other is configured as Legend-NTWK. See
the Network Reference for more information.
NOTE:
CCS is automatically assigned when PRI is selected. Also,
Channel 24 cannot be used for voice or data transmissions.
