TIE - S56 Data. Select when emulated tie trunks are used for Switched 56
Data Service. Switched 56 Data Service is available only in Release 4.0
and later.
If the type is T1 and S56 Data Network Service is selected, you must specify the
following parameters (Switched 56 Data Service is available only in Release 4.0
and later):
Direction. Specifies whether the trunk operates in one- or two-way
direction. For one-way trunks, Outgoing Only or Incoming Only must also
be specified.
Trunk Seizure Type. Trunk seizure type is administered independently for
incoming or outgoing directions. Select one of the following: Wink Start,
Delay Start, or Automatic Start.
Answer Supervision Time. The time in milliseconds the answer
supervision signal must be present to be considered valid.
Disconnect Time. The time in milliseconds the disconnect signal must be
present to be considered valid.
Dial Mode. Select either Rotary or Touch-Tone. Dial mode is set
independently for incoming or outgoing directions (Inmode or Outmode).

the valid range for each threshold.
If you select T1, channels can emulate ground- or loop-start trunks, tie trunks, or
DID trunks in any combination. Note that unused channels must be specified as
unequipped.
If either T1 or PRI is selected, channels can be used for ASN services. When T1
channels are used for ASN services, each channel must be programmed for tie
trunk emulation.
If you select PRI, you must also perform additional procedures. At a minimum, the
Framing Mode and Zero Code Suppression procedures must be performed. See
''PRI Facilities''
NOTE:
Touch-Tone receivers are required on the far-end switch when the
setting is Touch-Tone.
