4 If the trunk is ISDN, check the ISDN check box, and click ISDN Settings to configure the
ISDN trunk settings as follows:
Note: If you do not select the ISDN check box, the trunk will be a CAS (Channel Associated
Signaling) T-1 trunk, which implies robbed-bit signaling or clear channel for data. Clear
channels (whether ISDN or CAS) must be assigned to data connections, and channels
grouped for data connections must be contiguous. All other channel types, like B channels,
must be assigned to voice trunk groups. If you configure ISDN to use a voice trunk group,
you can configure that ISDN connection for dial-up data; see “Configuring dial-up routing”
on page 21-1.
a Select a variant in the
Switch Variant drop-down list.
Refer to your T-1 Service Confirmation Letter to determine which of the following
ISDN switch variants to use:
• AT&T 5ESS (Custom)
• AT&T 4ESS
• NT DMS-100 (NI-1)
• AT&T 4ESS (NI-2)
• NT DMS-100 /S-100
Select the NT DMS-100 /S-100 variant when connecting to a Northern Telecom
Meridian DMS-100 PBX configured with a subtype profile of S-100. In this scenario,
the DMS-100 must be configured as the network side. Wave is always the user side.
