until it receives a restart message when the control channel is on the same TDM
Bus PT or when this circuit pack is powered up again.
To force the system to send a restart message to all circuit packs on a network,
try one of the following methods depending on the circumstances:
NOTE:
A circuit pack functioning normally (that is, not in the reset state) ignores
the restart message.
Procedure 1 (Nondestructive)
Execute the Idle Time Slot Test (#294) by issuing the command test tdm P when
the control channel is on the same TDM Bus as it was when the circuit pack
entered the reset state. If using this method is not feasible, try the other
procedures in this section.
Procedure 2 (Non-Destructive)
if you are at the site: Reseat the circuit pack. This action causes the circuit pack
that was in the reset state to begin functioning on the
current Control Channel
bus.
Procedure 2 (Nondestructive)
Execute the Idle Time Slot Test (#294) by issuing the command test tdm P when
the control channel is on the same TDM Bus as it was when the circuit pack
entered the reset state. If using this method is not feasible, try the other
procedures in the section.
Procedure 3 (Destructive)
Reset the port network that contains the circuit pack that is in the reset state.
When a network is reset, two restart messages, one on the control channel of
each TDM Bus, are sent to each circuit pack on the network. Executing the reset
system L command (where L=2, 3, 4, or 5) resets all networks in the system.
To
reset an EPN only
, busyout all links to the EPN via the busyout board PCSS
command and then release them via the release board PCSS command.
!
WARNING:
The reset system command disrupts all calls in the system. Resetting the
EPN only disrupts all calls going to and originating from the EPN.
Procedure 4 (Destructive)
Execute the recycle carrier PC command where P is the Port Network Number
of the network containing the circuit pack and C is the designation of the carrier
containing the circuit pack.
