Enhanced Busy Lamp Field monitoring (example)
Operating parameters
Enough hundreds groups must be defined to support the maximum number
of telephones to be monitored. The maximum number of hundreds is 99.
The EBLF requires an M2250 attendant console equipped with a BLF/CGM.
The SBLF and the EBLF are incompatible.
The EBLF supports mixed dialing plans (4, 5, 6, or 7 digits), but each
hundreds group defined must be unique. For example, DNs 25XX and
25XXX cannot be configured in the same system. Any other DN group must
begin with something other than 25 because, in this case, the CGM would
be updated for DNs 2500 through 2599.
Only 20 attendant consoles can be updated for the same hundreds group
simultaneously. If more than 20 consoles are monitoring the status of
a single hundreds group, only the first 20 are updated. The remaining
consoles display the earlier status, and an error message is output at this
occurrence. (An unlimited number of consoles can be updated when they
display different hundreds groups.)
