Configuring a T1 or E1 Bearer Span
Click on Technical Notes for technical information when configuring the E1 Physical Span.
Specifies whether that specific span is used for primary loop timing, secondary loop timing or not.
Primary
Secondary
Not Timing Source
Specifies the line coding of that specific span:
AMI
HDB3
Specifies whether CRC4 error checking is enabled or disabled:
True
False
Specifies whether FEBE is enabled or disabled:
True
False
Specifies whether the E1 interface is 75 ohm or 120 ohm.
G.703 ITU-T (120 ohm)
G.703 ITU-T (120 ohm)
Clear Channel (Set this for SS7 and ISDN spans.)
CAS (Set this for CAS spans.)
E1 Layer 1 Mgmt
Euro-ISDN E1 Layer 1 Mgmt
Austel-ISDM E1 Layer 1 Mgmt
Specifies whether transmit all zeros is enabled or disabled.
True
False
Bearer or Signaling DS1’s can be configured for local or remote loopback. Each span offset must be individually configured.
No Loopback
Local Loopback
Remote Loopback
Note: When you place a span in loopback mode the Span Status will indicate Out Of Service. Following the test you must manually put the span back in service by selecting the In Service button.
See Loopback Testing for more information.
This monitoring field indicates the current status of the E1 span.
This button brings the E1 span in service.
Note: You must manually bring a span back in service following a loopback test.
This spans takes the E1 span out of service.
The table below shows the default format for E1 spans. You must enable Clear Channel signaling to use timeslot 16 as a voice channel for out-of-band signaling (for example, an ISDN application).
Note: Clear Channel signaling must be enabled to use timeslot 16 as a D channel in ISDN applications.
Note: For CAS, channel 16 will appear as Out of Service.
