Maintenance Commands

busyout ds1-facility

busyout ds1-facility UUCSSf [override]

This command puts a specified DS1 facility of a DS1C complex into a

maintenance busy state. Each DS1C complex uses from 1 to 4 DS1 facilities.

The packet facility carries the control channel for every facility in the

complex, all packet traffic, and some circuit connections.

The other facilities carry circuit connections only.

Whenever the circuit pack resets, the packet facility is set on the "a" facility. If

system software detects a problem with this facility, it switches the packet and

control traffic to another facility. The busyout command is not allowed on the

packet facility unless the override qualifier is used. When the override is used, all

packet and circuit traffic on the packet facility is switched to one of the other three

facilities; all traffic that was on the destination facility before the switch is dropped.

There is no way to tell which facility is carrying the packet and control traffic

without attempting to busy it out . If there is only one facility left in service on the

circuit pack, it cannot be busied out. In this case, the circuit pack must be busied

Busying out a non-packet facility disrupts all traffic carried on that facility.

Use of the override command to busy the packet facility disrupts all traffic on

the facility to which the packet and control traffic is moved. This facility

cannot be determined in advance.

On critical-reliability systems (duplicated PNC) a facility on the active PNC cannot

be busied out. To busyout a facility on the standby PNC, the standby PNC must

first be busied out by busyout pnc .
