66.11.6 PSTN Parameters
This subsection describes the device's PSTN parameters.
66.11.6.1 General Parameters
The general PSTN parameters are described in the table below.
General PSTN Parameters
Parameter Description
Web/EMS: Protocol Type
CLI: protocol
[ProtocolType]
Defines the PSTN protocol for all the Trunks. To configure the
protocol type for a specific Trunk, use the ini file parameter
ProtocolType_x:
 [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
Lucentâ„¢/AT&Tâ„¢ 4ESS switch.
 [12] T1 5ESS 9 ISDN = ISDN PRI protocol for the
Lucentâ„¢/AT&Tâ„¢ 5ESS-9 switch.
 [13] T1 5ESS 10 ISDN = ISDN PRI protocol for the
Lucentâ„¢/AT&Tâ„¢ 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).
 [17] E1 AUSTEL ISDN = ISDN PRI protocol for the Australian
Telecom.
 [18] E1 HKT ISDN = ISDN PRI (E1) protocol for the Hong
Kong - HKT.
