should match what your central office provides. Refer to ‘‘Types of address 
transmission’’ on page 1572 for more information. This field appears for Access, 
APLT, DID, DIOD, DMI-BOS, FX, RLT, Tandem,...

The value in this field affects the appearance of the Incoming Partial Dial 
(sec) field on the Administrable Timer Page.

This field appears when the “out” side of the entry in the Trunk Type (in/out) field 
is 
…/wink or …/delay and the Group Type is tie, access, aplt, dmi-bos, rlt, or 
tandem. The setting in this field only affects trunks administered to ports on 
TN760C (vintage 4 or later), TN767, TN464C (or later), and TN2242 circuit 
packs. If the trunk group also contains trunks assigned to ports on...

End-to-End Signaling
Auxiliary equipment such as paging equipment and music sources may be 
connected to DEFINITY ECS by auxiliary trunks. The switch may send DTMF 
signals (touch tones) to these devices. This field, which appears for CPE 
(customer-provided equipment) trunk groups, sets the duration of these tones.
NOTE:
For trunks that do not receive real answer supervision, a “connect”...

NOTE:
In a DCS network, DCS features that use the remote-tgs button (on phones 
at a remote switch) do not work when the incoming trunk group at your 
switch deletes or inserts digits on incoming calls. The remote-tgs button on a 
remote switch, for example, tries to dial a TAC on your switch. If your 
switch adds or deletes digits, it defeats this operation. If you need to 
manipulate...

Auto Guard
This field controls ports only on TN438B, TN465B, and TN2147 circuit packs. 
TN438B ports have hardware support for detecting a defective trunk. TN465B and 
TN2147 ports consider a trunk defective if no dial tone is detected on an outgoing 
call, and the Outpulse Without Tone field is 
n on the Feature-Related System 
Parameters screen. 
Call Still Held
This field is used when...

the default, you may need to invert one or both bits — to change “1” to “0” and 
vice-versa in the A-bit, for example. 
Analog Loss Group
This field determines which administered 2-party row in the loss plan applies to 
this trunk group if the call is carried over an analog signaling port in the trunk 
group. 
Digital Loss Group
This field determines which administered 2-party row in the...

Unless one or more trunk members are administered, the administered value 
is not saved when you submit the screen (press 
ENTER).

Extended Loop Range
This field appears only for a DID trunk group and is used only with the TN459A 
circuit pack. Enter 
y or n depending on the distance between the central office and 
the switch. If greater than the required distance, then the field should be 
y.
Trunk Gain
This field specifies the amplification applied to the trunks in this group. With the 
values of the Trunk...

Bit Rate
This field specifies the baud rate to be used by pooled modems. This field appears 
when the Comm Type field is 
avd or rbavd. It also appears if the Comm Type 
field is 
data, but only if the ISDN-PRI field is y on the System-Parameters 
Customer-Options screen.
Synchronization
This field determines whether the trunk group will use synchronous or 
asynchronous communications....
