Configuration Settings: Line
· 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.
· CSU Operation
Tick this field to enable the T1 line to respond to loop-back requests from the line.
· Haul Length: Default = 0-115 feet
Sets the line length to a specific distance.
· Channel Unit: Default = Foreign Exchange
This field should be set to match the channel signaling equipment provided by the Central Office. The options are
Foreign Exchange, Special Access or Normal.
· CRC Checking: Default = On
Turns CRC on or off.
· Line Signaling:
The field can be set to either CPE (Customer Premises Equipment) or CO (Central Office). This field should normally be
left at its default of CPE. The setting CO is normally only used in lab back-to-back testing.
· Incoming Routing Digits: Default=0 (present call immediately)
Sets the number of routing digits expected on incoming calls. This allows the line to present the call to the system once
the expected digits have been received rather than waiting for the digits timeout to expire. This field only affects T1
line channels set to E&M Tie, E&M DID, E&M Switched 56K and Direct Inward Dial.
· Admin: Default = In Service.
This field allows a trunk to be taken out of service if required for maintenance or if the trunk is not connected.
