Figure 7-12. Procedure 100 Word 3: Trunk Group/Trunk Type — Signaling Type Translations
Specifies a trunk group. Permitted entries include any not already used number
within the range of 18 to 999.
Administers or changes the signaling type for the trunk group.
For all ISDN trunking applications except DCS, glare is resolved by the ISDN
protocol. Glare is discussed in more detail in the chapter entitled "Network
Connections and Configurations" in this document. Specifically, ISDN negotiates
the losing call to a different channel if the original channel is preferred. Exclusive
calls (such as DCS) are not negotiated and the user hears the reorder tone. In either
case, the network has priority over the user when both calls are preferred or
exclusive. This capability is administered in procedure 262, word 1, and field 5.
Therefore, this field 3 entry may be any of the available encodes (0, 1, or 2) since
this field is ignored for ISDN applications.
