Attribute Value
• DS/CLID: displays for old North American LS/DS or CLID analog trunk modules, the old analog
MBM, or the GATM with North American DIP switch settings.
• Global: displays for the GATM MBM with no regional DIP switches set.
• Legacy: displays for all other (old) analog trunk modules
Protocol NI-2, DMS-100,
DMS-250,
AT&T4ESS, SL-1,
Euro, ETSI Q.Sig
Choose the trunk protocol used by your service provider.
The supported protocols are:
PRI-T1: NI (NI-1 and NI-2), DMS-100, DMS-250, AT&T4ESS, SL-1
PRI-E1: ETSI QSIG, Euro, SL-1
Note: SL-1 and ETSI QSIG require an MCDN keycode to display.
BRI: Protocol can also be selected on BRI T-loops under Configuration > Telephony > Loops.
Note: Always check the line protocol with the central office.
NSF Extension None, WATS, ALL
The Network Specific Facilities (NSF) information element is used to request a particular service from
the network. Settings are based on the type of switch to which the line connects.
Suggested settings:
DMS-100/250: NONE
Siemens ESWD, Lucent 5ESS: WATS
GTD5, DMS-10: ALL
When you select NONE, the NSF extension bit is not set for any service.
When you select WATS, the NSF extension bit is set for unbanded OUTWATS calls.
When you select ALL, the NSF extension is always set for all CbC services.
Appears only for NI protocol.
Protocol type User, Network
When you select SL-1 protocol, an additional setting, Protocol type, appears.
SL-1 protocol is a private networking protocol. Use this protocol to designate a BCM node as a
Network (controller). The default setting is User (client). In public network configurations, the CO is
generally considered the Network side or controller.
Applies to SL-1 protocol only.
B-channel Ascending Sequential
selection Descending
sequence Sequential
Defines how B-channel resources are selected for call processing.
Answer timer 1, 2, 3, 4, or 5 sec.
Set the minimum duration of an answer signal before a call is considered to be answered.
