ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 85
Fields 6-7
Selects in/out touch-tone availability. Field encodes and their descriptions are:
0
1
When only rotary pulses are received via the trunk group
When either rotary pulses or tough-tone can be accepted
NOTE: The ISDN-PRI applications use the D-channel to transmit and
receive dialed digits. Dialed digits are transmitted as ASCII characters.
Therefore, for ISDN applications, this field is ignored; either option may be
translated.
Field 8
Assigns the trunk group to SMDR record keeping. Field encodes and their
descriptions are:
0
1
2
Trunk group usage not applicable for SMDR recording
Trunk group usage will be recorded by SMDR
Trunk group usage will be recorded, account code is required
Fields 9-11
Not used for ISDN applications.
Field 12
This field is only applicable when SMDR is being used, and then only to change the
default SMDR timer value. Field encodes represent intervals in l-second
increments. The range is 1 through 99 with dash (–) being the default timer value
of 6 seconds.
Field 13
Administers the optional transmission loss assignments. The encode translated
depends on the network configuration and service application. Field encodes and
their corresponding loss plan are listed as follows:
0
1
2
3
4
5
6

ISL Tie Trunk
EIA Tie Trunk
NOTE: This is the recommended option for Special Access Connections to
a 4ESS.
ISL Digital Central Office
EIA Digital Central Office
Digital Toll Office
Analog Toll Office
AUTOPLEX NETWORK Interface V
AUTOPLEX NETWORK Interface Y
Refer to chapter 4, The Digital Loss Plan, for a description of the digital loss plan
and to table 4-2, Digital Loss Plan (Port-to-Port Losses), in this same chapter for a
list of port-to-port loss values.
Field 14
Assigns whether a trunk is toll restricted (1) or unrestricted (0).
NOTE: This field is ignored by the ISDN software. Either encode is
satisfactory.
