service-module t1 timeslots
To define timeslots that constitute a fractional T1/T1 (FT1/T1) channel, use the service-module t1 timeslots interface configuration command. To resume the default setting (all FT1/T1 timeslots transmit at 64 kbps), use the no form of this command.
service-module t1 timeslots {range | all} [speed {56 | 64}]
no service-module t1 timeslots {range | all}
Syntax Description
Defaults
64 kbps is the default for all timeslots.
Command Modes
Interface configuration
Command History
Usage Guidelines
This command specifies which timeslots are used in fractional T1 operation and determines the amount of bandwidth available to the router in each FT1/T1 channel.
The timeslot range must match the timeslots assigned to the channel group. Your service provider defines the timeslots that comprise a channel group.
To use the entire T1 line, enable the service-module t1 timeslots all command.
Examples
The following example displays a series of timeslot ranges and a speed of 64 kbps:
Router(config-if)# service-module t1 timeslots 1-10,15-20,22 speed 64Related Commands
Guarantees the ones density requirement on an AMI line using the fractional T1/T1 module.
Selects the linecode for the fractional T1/T1 module.
show aps
To display information about the current automatic protection switching (APS) feature, use the show aps privileged EXEC command.
show aps
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Examples
The following is an example of the show aps command on a router configured with a working interface. In this example, POS interface 0/0/0 is configured as a working interface in group 1, and the interface is selected (that is, active).
router1# show apsPOS0/0/0 working group 1 channel 1 Enabled SelectedThe following is an example of the show aps command on a router configured with a protect interface. In this example, POS interface 2/0/0 is configured as a protect interface in group 1, and the interface is not selected (the ~ indicates that the interface is not active). The output also shows that the working channel is located on the router with the IP address 15.1.6.1 and that the interface is currently selected (that is, active).
router2# show apsPOS2/0/0 protect group 1 channel 0 bidirectional ~SelectedRx_K1= 0, Rx_K2= 0 Tx_K1= 0 Tx_K2= 5Working channel 1 at 15.1.6.1 EnabledFor the K1 field (8 bits), the first 4 bits indicate the channel number that has made the request, and the last 4 bits map to the requests (local or external) listed in Table 14. For the K2 field (8 bits), the first 4 bits indicate the channel number bridged onto the protect line, the next bit is the architecture used, and the last 3 bits indicate the mode of operation or non-APS use listed in Table 14.
show compress
To display compression statistics, use the show compress EXEC command.
show compress
Syntax Description
This command has no arguments or keywords.
Command Modes

Command History
10.0
This command was introduced.
11.3
An example for hardware compression (implemented in the CSA hardware) was added.
Examples
The following is an example from the show compress command when software compression is used on the router:
Router# show compressSerial0uncompressed bytes xmt/rcv 10710562/113768351 min avg ratio xmt/rcv 2.773/2.4745 min avg ratio xmt/rcv 4.084/3.79310 min avg ratio xmt/rcv 4.125/3.873no bufs xmt 0 no bufs rcv 0resets 0Table 15 describes the fields shown in the display.
The following is an example from the show compress command when hardware compression is enabled (that is, compression is implemented in the CSA hardware):
Router# show compressSerial6/1Hardware compression enabledCSA in slot3 in useCompressed bytes sent: 402 bytes 0 Kbits/sec ratio: 4.092Compressed bytes recv: 390 bytes 0 Kbits/sec ratio: 3.476restarts:1last clearing of counters: 1278 secondsTable 16 describes the fields shown in the display. The information displayed by the show compress command is the same for hardware and distributed compression. For Cisco 7200 series routers with multiple CSAs, an additional line is displayed indicating the CSA in use.

show controllers cbus
To display all information under the cBus controller card, use the show controllers cbus privileged EXEC command on the Cisco 7500 series routers. This command also shows the capabilities of the card and reports controller-related failures.

The ECA hardware version and the resyncs field were added to CIP output.
Usage Guidelines
Verifying the ECA Hardware Version
The following partial sample output shows how the ECA hardware version is displayed:

Sometimes the IPs may not respond within this time due to heavy traffic or some problem in the IP's hardware or firmware. Then the IP's response to cBus commands may be out of sync. When this situation occurs, the Route Processor (RP) must resync the IP. Currently CIP, FSIP, FEIP, RVIP, and SVIP support the resync mechanism.Table 17 describes significant fields shown in the display.
Note
The timeouts, resyncs, and max phase count values do not imply any problem in the IP. The failures value implies a problem and usually end in a console error message.
The following is a partial example from the show controllers cbus command on a Cisco 7500 series router with one VIP2 interface processor. This example does not show output from additional interface processors that are usually installed in a Cisco 7500 series router.

show controllers fddi
To display all information under the FDDI Interface Processor (FIP) on the Cisco 7200 series and Cisco 7500 series routers, use the show controllers fddi user EXEC command.
show controllers fddi
Syntax Description
This command has no arguments or keywords.
Command Modes
User EXEC
Command History
Usage Guidelines
This command reflects the internal state of the chips and information the system uses for bridging and routing that is specific to the interface hardware. The information displayed is generally useful for diagnostic tasks performed by technical support personnel only.
