Version 6.4 685 March 2012
SIP User's Manual A. Configuration Parameters Reference
Parameter Description
[ClockMaster_x]
Same as the description for parameter ClockMaster, but for a
specific Trunk ID (where x denotes the Trunk ID and 0 is the first
Trunk).
Web/EMS: Line Code
[LineCode]
Selects B8ZS or AMI for T1 spans, and HDB3 or AMI for E1 spans.
[0] B8ZS = use B8ZS line code (for T1 trunks only) default.
[1] AMI = use AMI line code.
[2] HDB3 = use HDB3 line code (for E1 trunks only).
Note: This parameter is not configurable for BRI interfaces; the
device automatically uses the Modified Alternate Mark Invert
(MAMI) line code.
[LineCode_x]
Same as the description for parameter LineCode, but for a specific
trunk ID (where 0 denotes the first trunk).
[TrunkLifeLineType]
Determines the scenarios upon which the PSTN Fallback (lifeline)
feature is activated. This feature redirects IP calls to the PSTN
upon a power outage, a LAN disconnection, or lack of IP
connectivity (i.e., no ping), thereby guaranteeing call continuity.
PSTN Fallback is supported if the device houses one or two E1/T1
("TRUNKS") modules, where each module provides two or four
spans. In the event of a PSTN fallback, the module's metalic relay
switch automatically connects trunk Port 1 (I) to Port 2 (II), and / or
trunk Port 3 (III) to Port 4 (IIII), of the same module.
Therefore, if for example, a PBX trunk is connected to Port 1 and
the PSTN network is connected to Port 2, when PSTN fallback is
activated, calls from the PBX are routed directly to the PSTN
through Port 2.
[0] = Activate PSTN Fallback upon power outage (default).
[1] = Activate PSTN Fallback upon power outage or detection of
LAN disconnection.
[2] = Activate PSTN Fallaback on power outage, detection of
LAN disconnection, or loss of ping (i.e., no IP connectivity).
Notes:
For this parameter to take effect, a device reset is required.
PSTN Fallback is supported only between ports on the same
module.
PSTN Fallback is supported only for ISDN when the number of
supported channels (e.g., 30) is less than the maximum number
of possible channels provided by the physical ports (e.g., two E1
trunks). When the number of supported channels (e.g., 60)
equals the maximum number of channels provided by the
physical ports (e.g., two E1 trunks), then other protocols such as
CAS are also supported.
The PSTN Fallback feature has no relation to the PSTN
Fallback Software Upgrade Key.
[AdminState]
Defines the administrative state for all trunks.
[0] = Lock the trunk; stops trunk traffic to configure the trunk
protocol type.
[1] = Shutting down (read only).
[2] = Unlock the trunk (default); enables trunk traffic.
