Summary
The “e1span” command allows you to view or modify a span record for E1 and T1 PRI systems.
Description
The “e1span” command is used to view or modify an E1 or T1 PRI span record in the database. This tells
the system whether the span should be active, various characteristics of the span, and the mapping
between trunks and internal port numbers.
the system whether the span should be active, various characteristics of the span, and the mapping
between trunks and internal port numbers.
The following characteristics are set by the “e1span” command:
•
Timing external or internal. This determines whether the span is permitted to supply trunk timing
for the system. Specify external if the span is connected to the public network or a trusted system.
At least one span should always be designated external.
for the system. Specify external if the span is connected to the public network or a trusted system.
At least one span should always be designated external.
•
External sync priority. A number (1-255) or never. This controls the priority (1 is highest, 255 is
slowest) of the spans that are set for external timing. The system picks the highest priority
operational span to provide timing. If two spans have the same priority, the lowered numbered span
wins.

Options
After typing
e1span
and pressing Enter, the following menu appears:
•
1) View ACTI span record(s) — prompts the user to select a specific span or all spans. The system
then prints whether the span is active, the characteristics of the span, and the port number for each
trunk.

•
x) Exit — exits the “e1span” utility command.
Note
E1 spans are numbered 0-31. Trunks on a span are numbered 1-30. Ports are numbered for the number
of licensed access ports minus 1. There are up to 16 span records for each Multi Access Blade. The span
record is referenced by both parameters set using the “e1card” command and parameters set using the
“blade” command. It is important to be sure that these references are consistent. If a port is referenced
in a span record, the corresponding port record must reference that span.

If the Multi Access Blade is not active, then the 16 spans will not operate even if they are set to active

Note
Changes to a span record will only take effect after the next system restart.
