Configuration Settings: Line
· Outgoing Channels
This defines the number of channels available, on this line, for outgoing calls. This should normally be the same as
Number of Channels field, but can be reduced to ensure incoming calls cannot be blocked by outgoing calls. Only
available when the Line Sub Type is set to ETSI.
· Voice Channels
The number of channels available for voice use. Only available when the Line Sub Type is set to ETSI.
· Data Channels
The number of channels available for data use. Only available when the Line Sub Type is set to ETSI.
· CRC Checking: Default = On
Switches CRC on or off.
· Line Signalling: Default = CPE
This option is not used for lines where the Line SubType is set to QSIG. Select either CPE (customer premises
equipment) or CO (central office). The CO feature is intended to be used primarily as a testing aid. It allows PRI lines
to be tested in a back-to-back configuration, using crossover cables.
· The CO feature operates on this line type by modifying the way in which incoming calls are disconnected for system
configuration in Brazil and Argentina. In these locales, the CO setting uses Forced-Release instead of Clear-Back to
disconnect incoming calls. The Brazilian Double-Seizure mechanism, used to police Collect calls, is also disabled in
CO mode.
· Clock Quality: Default = Network
Refer to the Avaya Branch Gateway Installation Manual for full details. This option sets whether the system should try
to take its clock source for call synchronization and signalling from this line. Preference should always be given to using
the clock source from a central office exchange if available by setting at least one exchange line to Network.
· If multiple lines are set as Network, the order in which those lines are used is described in the Avaya Branch
Gateway Installation Manual. If additional lines are available, Fallback can be used to specify a clock source to
use should the Network source not be available.
· Lines from which the clock source should not be taken should be set as Unsuitable.
· If no clock source is available, the system uses its own internal 8KHz clock source.
· In scenarios where several systems are network via digital trunk lines, care must be taken to ensure that all the
systems use the same clock source. The current source being used by a system is reported within the System
Status Application.
· Add 'Not-end-to-end ISDN' Information Element: Default = Never*.
Sets whether the optional 'Not end-to-end ISDN' information element should be added to outgoing calls on the line.
The options are Never, Always or POTS (only if the call was originated by an analog extension). *The default is
Never except for the following locales; for Italy the default is POTS, for New Zealand the default is Always.
· Supports Partial Rerouting: Default = Off.
Partial rerouting (PR) is an ISDN feature. It is supported on external (non-network and QSIG) ISDN exchange calls.
When an external call is transferred to another external number, the transfer is performed by the ISDN exchange and
the channels to the system are freed. Use of this service may need to be requested from the line provider and may
incur a charge.
· Force Number Plan to ISDN: Default = Off.
This option is only configurable when Support Partial Rerouting is also enabled. When selected, the plan/type
parameter for Partial Rerouting is changed from Unknown/Unknown to ISDN/Unknown.
· Send Redirecting Number: Default = Off.
This option can be used on ISDN trunks where the redirecting service is supported by the trunk provider. Where
supported, on twinned calls the caller ID of the original call is passed through to the twinning destination. This option is
only used for twinned calls.
· Support Call Tracing: Default = Off.
The system supports the triggering of malicious caller ID (MCID) tracing at the ISDN exchange. Use of this feature
requires liaison with the ISDN service provider and the appropriate legal authorities to whom the call trace will be
passed. The user will also need to be enabled for call tracing and be provider with either a short code or programmable
button to activate MCID call trace. Refer to Malicious Call Tracing in the Telephone Features section for full details.
· Active CCBS Support: Default = Off.
Call completion to a busy subscriber (CCBS). It allows automatic callback to be used on outgoing ISDN calls when the
destination is busy. This feature can only be used on point-to-point trunks. Use of this service may need to be
requested from the line provider and may incur a charge.
· Passive CCBS: Default = Off.
· Cost Per Charging Unit:
Advice of charge (AOC) information can be output in SMDR . The information is provided in the form of charge
units. This setting is used to enter the call cost per charging unit set by the line provider. The values are 1/10,000th of
a currency unit. For example if the call cost per unit is £1.07, a value of 10700 should be set on the line. Refer to
Advice of Charge.
· Admin: Default = In Service.
