Line | Channels (E1-R2)

This tab allows settings for individual channels within the trunk to be adjusted. To edit a channel, select the required channel or channels and click Edit.

Settings

The channel settings are split into two sub-tabs, E1R2 Edit Channel and Timers.

E1R2 Edit Channel Settings

• Channel
  The channel or channels being edited.

• Incoming Group ID: Default = 0, Range 0 to 99999.
  The Incoming Group ID to which a line belongs is used to match it to incoming call routes in the IP Office configuration. The matching incoming call route is then used to route incoming calls. The same ID can be used for multiple lines.

• Outgoing Group ID: Default = 0, Range 0 to 99999.
  Short codes that specify a number to dial also specify the line group to be used. The IP Office will then seize a line with a matching Outgoing Group ID. The same ID can be used for multiple lines.

• Line Appearance ID: Default = Blank, Range = 2 to 9 digits.
  [2.1 ][3.0DT ][3.0 ][3.1 ][3.2 ]
  Though line appearance settings are shown for E1R2 trunks, use of line appearances with E1R2 is not supported.

• Direction: Default = Both Directions
  The direction of calls on the channel (Incoming, Outgoing or Both Directions).

• Bearer: Default = Any
  The type of traffic carried by the channel (Voice, Data or Any).

• Line Signaling Type: Default = R2 Loop Start
  The signaling type used by the channel. Current supported options are: R2 Loop Start, R2 DID, R2 DOD, R2 DIOD, Tie Immediate Start, Tie Wink Start, Tie Delay Dial, Tie Automatic, WAN Service and Out of Service.

• Dial Type: Default = MFC Dialing
  The type of dialing supported by the channel; MFC Dialing,Pulse DialingorDTMF Dialing.

Timers Settings

This sub-tab displays the various timers provided for E1-R2 channels. These should only be adjusted when required to match the line provider's settings.

Line | MFC Group (E1-R2)

These tabs show the parameter assigned to each signal in an MFC group. The defaults are set according to the Country (Locale) on the Line tab. All the values can be returned to default by the Default All button on the Advanced tab.

To change a setting either double-click on it or right-click and select Edit.

Line | Advanced (E1-R2)

Settings

• Zero Suppression: Default = HDB3
  Selects the method of zero suppression used (HDB3 or AMI).

• Clock Quality: Default = Network
  Sets whether the IP Office takes it clock source for call synchronization and signalling from this line. One line connected to the IP Office should be set to Network. and wherever possible this should be a line connected to the central office exchange. Another line can be set to Fallback but all other lines should be set to Unsuitable.  

• Pulse Metering Bit: Default = A Bit
  Sets which bit should be used to indicate the pulse metering signal; A Bit, B Bit or C Bit.

• Line Signaling: Default = CPE
  Select either CPE or CO. The CO feature is intended to be used primarily as a testing aid. It allows T1 and E1 lines to be tested in a back-to-back configuration, using crossover (QSIG) cables.

• The CO feature operates by modifying the way in which incoming calls are disconnected for IP Office 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.

• Incoming Routing Digits: Default = 4
  Sets the number of incoming digits used for incoming call routing.

• CRC Checking: Default = Ticked (On)
  Switches CRC on or off.

• Default All Group Settings
  Default the MFC Group tab settings.

• Line Signaling Timers:
  To edit one of these timers, either double-click on the timer or right-click on a timer and select the action required.
