Resolving Bearer Channel Connection Problems
To set the administrative state of a bearer channel or a range of bearer channels in a span, perform the
following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
rtrv-admin-state: sig_srv :span= x ,bc= y [,rng= range ]: state command:
Where:
• sig_srv—MML name of the signaling service. The following signaling service types are valid for
this command:
– In-band TDM up to MUX and then time switched to TDM media and sent to the Cisco PGW
2200 Softswitch.
– In-band TDM signaling up to CU and then encapsulated and sent over IP to the Cisco PGW 2200
Softswitch.
– In-band TDM signaling up to the media gateway and then converted to NI2 and sent to the
Cisco PGW 2200 Softswitch over IP (that is, FE box<-sig/tdm->media gateway<-NI2/IP->
Cisco PGW 2200 Softswitch).
– Signaling service or routeset that is associated with a DPC.
– EISUP signaling service.
• x—16-bit value that identifies an ISDN/PRI physical cable.
• y—Numeric value that identifies the non-ISUP bearer channel number.
• range—A value such that y+range is a valid bearer channel number. The administrative state for all
bearer channels between y and y+range are retrieved.
• state—Administrative state. The following states are valid:
– Lock—Makes the specified bearer channels unavailable for call processing. If the state is set to
lock, active calls on the affected bearer channels go into pending state, where calls remain until
either party voluntarily releases the call. New calls are disallowed on the affected bearer
channels.
– Unlock—Makes the specified bearer channels available for call processing. If the state is set to
unlock, the bearer channels become available. New calls are allowed to use the affected bearer
channels.
For example, to set the administrative state of bearer channel numbers 2 through 6, associated with a
signaling service called ss7svc1, to unlock, enter the
rtrv-admin-state:ss7svc1:span=2,bc=2,rng=5:unlock command.
Step 2 Verify that the state of the bearer channels changed by entering the rtrv-admin-state MML command,
as described in the “Retrieving the Administrative State of Spans” section on page 3-57.
Setting the Administrative State of CICs
To set the administrative state of a CIC or a range of CICs, perform the following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
set-admin-state: sig_srv :cic= number [,rng= range ]: state command.
