Configuring a T1 or E1 Bearer Span
Click on Technical Notes link for technical information on the T1 Physical Span
When configuring an E1 Physical Span, a T1 logical span ID is configured for the TDM DS1 offset, the logical span ID is based on the following formulas:
Bearer span IDs = (32*Logical_Node_ID) + Physical_Offset
Signaling span IDs = (32*Logical_Node_ID) + 28 + Physical_Offset
It also configures the format of the T1 span based on the parameters selected for the T1 Physical Span offset.
Specifies whether that specific span is used for primary loop timing, secondary loop timing or not.
Primary
Secondary
Not Timing Source
Specifies whether the framing of the span is ESF or D4.
ESF
D4
Clear Channel
CAS
Specifies the length of the T1 line:
0-133 ft
134-166 ft
167-299 ft
300-533 ft
534-655 ft
NOTE: In SNMP, the first value in the range is returned, in meters, as shown below:
0-133 ft = 0
134-166 ft = 41
167-299 ft = 51
300-533 ft = 91
534-655 ft = 163
Specifies the line coding of T1 span.
Bit 7 zero suppressing
B8ZS zero suppressing
NOTE: For T1 SS7 links with line coding configured for B7ZS, only the 48 Kbps data rates (configured in the SS7 Link pane) are valid.
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 T1 span in service.
NOTE: You must manually bring a span back in service following a loopback test.
This spans takes the T1 span out of service.
