Protocol NI-2, DMS100,
DMS250,
AT&T4ESS, SL-1,
Euro, ETSI Q-Sig
PRI
Choose the trunk protocol used by your service provider.
The supported protocols are:
PRI-T1: NI-2, DMS100, DMS250, 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 the Services/Telephony/Loops
heading.
Note: Always check the line protocol with the central office.
Protocol type User, Network
PRI
When you select SL-1 protocol, an additional setting, Protocol type, appears.
SL-1 protocol is a private networking protocol. This allows you to designate a Business
Communications Manager node as a Network (Master). The default setting is User (Slave).
In public network configurations, the CO is generally considered the Network side or
Master.
Applies to SL-1 protocol only.
NSF
Extension None, WATS, ALL
PRI
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:
DMS100/250: NONE
Siemens ESWD, Lucent 5ESS: WATS
GTD5, DMS10: 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-2 protocol.
