protocol
[ProtocolType]
Defines the PSTN protocol for the trunk.
■ [0] NONE
■ [1] E1 EURO ISDN = ISDN PRI Pan-European (CTR4)
protocol
■ [2] T1 CAS = Common T1 robbed bits protocols including
E&M wink start, E&M immediate start, E&M delay
dial/start and loop-start and ground start.
■ [3] T1 RAW CAS
■ [4] T1 TRANSPARENT = Transparent protocol, where no
signaling is provided by the device. Timeslots 1 to 24 of all
trunks are mapped to DSP channels.
■ [5] E1 TRANSPARENT 31 = Transparent protocol, where
no signaling is provided by the device. Timeslots 1 to 31 of
each trunk are mapped to DSP channels.
■ [6] E1 TRANSPARENT 30 = Transparent protocol, where
no signaling is provided by the device. Timeslots 1 to 31,
excluding time slot 16 of all trunks are mapped to DSP
channels.
■ [7] E1 MFCR2 = Common E1 MFC/R2 CAS protocols
(including line signaling and compelled register signaling).
■ [8] E1 CAS = Common E1 CAS protocols (including line
signaling and MF/DTMF address transfer).
■ [9] E1 RAW CAS
■ [10] T1 NI2 ISDN = National ISDN 2 PRI protocol
■ [11] T1 4ESS ISDN = ISDN PRI protocol for the
Lucent™/AT&T™ 4ESS switch.
■ [12] T1 5ESS 9 ISDN = ISDN PRI protocol for the
Lucent™/AT&T™ 5ESS-9 switch.
■ [13] T1 5ESS 10 ISDN = ISDN PRI protocol for the
Lucent™/AT&T™ 5ESS-10 switch.
■ [14] T1 DMS100 ISDN = ISDN PRI protocol for the
Nortel™ DMS switch.
■ [15] J1 TRANSPARENT
■ [16] T1 NTT ISDN = ISDN PRI protocol for the Japan -
Nippon Telegraph Telephone (known also as INS 1500).
