62.10.6 PSTN Parameters
This subsection describes the device's PSTN parameters.
62.10.6.1 General Parameters
The general PSTN parameters are described in the table below.
Table 62-56: General PSTN Parameters
Parameter Description
Trunk Name
config-voip > interface
<e1|t1|bri> name
[DigitalPortInfo_x]
Defines an arbitrary name for a trunk (where x denotes the trunk
number for the ini file parameter). This can be used to help you
easily identify the trunk.
The valid value is a string of up to 40 characters. The following
special characters can be used (without the quotes):
 " " (space)
 "." (period)
 "=" (equal sign)
 "-" (hyphen)
 "_" (underscore)
 "#" (pound sign)
By default, the value is undefined.
Protocol Type
configure voip > interface e1-
t1|bri > 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.
