clear interface virtual-access
channel-group
To define the time slots that belong to each T1 or E1 circuit, use the channel-group command in controller configuration mode. To clear the time slots for the T1 or E1 circuit, use the no form of this command.
channel-group channel-number timeslots range [speed {48 | 56 | 64}]
no channel-group [channel-number timeslots range]
Syntax Description
Defaults
The default line speed when configuring a T1 controller is 56 kbps.
The default line speed when configuring an E1 controller is 64 kbps.
Command Modes
Controller configuration
Command History
Usage Guidelines
Use this command in configurations where the router or access server must communicate with a T1 or E1 fractional data line. The channel-group number may be arbitrarily assigned and must be unique for the controller. The time slot range must match the time slots assigned to the channel group. The service provider defines the time slots that comprise a channel group.
Note
Channel groups, CAS voice groups, and TDM groups all use group numbers. All group numbers configured for channel groups, CAS voice groups and TDM groups must be unique on the local Cisco MC3810 concentrator. For example, you cannot use the same group number for a channel group and for a TDM group. Furthermore, on the Cisco MC3810 concentrator, only one channel group can be configured on a controller.
If you specify 56 kbps, the channel group is limited to 14 channels on the Cisco MC3810 MultiFlex Trunk (MFT). Because the 56 keyword is the default, specify the 64 keyword when you need more than 14 channels.
The channel-group command also applies to Voice over Frame Relay, Voice over ATM, and Voice over HDLC on the Cisco MC3810.
Examples
The following example defines three channel groups. Channel-group 0 consists of a single time slot, channel-group 8 consists of 7 time slots and runs at a speed of 64 kbps per time slot, and channel-group 12 consists of a single time slot.
channel-group 0 timeslots 1channel-group 8 timeslots 5,7,12-15,20 speed 64channel-group 12 timeslots 2The following example configures a channel group on controller T1 0 on a Cisco MC3810:

framing
Selects the frame type for the T1 or E1 data line.
linecode
Selects the linecode type for T1 or E1 line.
chat-script
To create a script that will place a call over a modem, use the chat-script command in global configuration mode. To disable the specified chat script, use the no form of this command.
chat-script script-name expect-send
no chat-script script-name expect-send
Syntax Description
script-name
Name of the chat script.
expect-send
Pairs of information elements: an item to expect and an item to send in response.
Defaults
No chat scripts are defined.
Command Modes
Global configuration
Command History
Usage Guidelines
Chat scripts are used in dial-on-demand routing (DDR) to give commands to dial a modem and commands to log on to remote systems. The defined script will be used to place a call over a modem.
Some characteristics of chat scripts are as follows:
•
•
•
•
We recommend that one chat script (a "modem" chat script) be written for placing a call and another chat script (a "system" or "login" chat script) be written to log on to remote systems, where required.
Suggested Chat Script Naming Conventions
A suggested chat script naming convention is vendor-type-modulation. If you follow this convention, the syntax of the chat-script command becomes chat-script vendor-type-modulation expect-send.
For example, if you have a Telebit T3000 modem that uses V.32bis modulation, you would name your chat script telebit-t3000-v32bis.
The chat-script command could be written as follows:
chat-script telebit-t3000-v32bis ABORT ERROR ABORT BUSY ABORT "NO ANSWER" "" "AT H" OK "AT DT \T" DIALING \c TIMEOUT 30 CONNECT \cAdhering to this naming convention allows you to use partial chat script names with regular expressions to specify a range of chat scripts that can be used. This capability is particularly useful for dialer rotary groups and is explained further in the next section.
Chat scripts are in the form expect-send, where the send string following the hyphen (-) is executed if the preceding expect string fails. Each send string is followed by a return unless it ends with the escape sequence \c. The sequence ^x is translated into the appropriate control character, and the sequence \x is translated into x if \x is not one of the special sequences listed in Table 5.
See the book titled Managing uucp and Usenet by Tim O'Reilly and Grace Todino for more information about chat scripts.
Escape Sequences
The escape sequences used in chat scripts are listed in Table 5.
Expect-Send Pairs
Sample supported expect-send pairs are described in Table 6.
For example, if a modem reports BUSY when the number dialed is busy, you can indicate that you want the attempt stopped at this point by including ABORT BUSY in your chat script.
Alternate Handlers
If you use the expect-send pair ABORT SINK instead of ABORT ERROR, the system terminates abnormally when it encounters SINK instead of ERROR.
Missed Characters
After the connection is established and you press the Return key, you must often press Return a second time before the prompt appears.
For example, you might include the following as part of your chat script:
ssword:-/r-sswordThis part of the script specifies that, after the connection is established, you want ssword to be displayed. If it is not displayed, you must press Return again after the timeout passes.
Examples
The following example shows the chat-script command being used to create a chat script named t3000:
chat-script t3000 ABORT ERROR ABORT BUSY ABORT "NO ANSWER" "" "AT H" OK "AT DT \T" DIALING \c TIMEOUT 60 CONNECT \cRelated Commands
class
To create a signaling class structure that can be referred to by its name, use the class command in controller configuration mode. To remove the structure, use the no form of this command.
class name
no class name
Syntax Description
Defaults
No default behavior or values.
Controller configuration
Command History
Usage Guidelines
A signalling class allows the Cisco AS5300 and Cisco AS5800 universal access servers to provide the ANI/DNIS delimiter on incoming T1/CAS trunk lines. The digit collection logic in the call switching module (CSM) for incoming T1 CAS calls in dual tone multifrequency (DTMF) is modified to process the delimiters, the ANI digits, and the DNIS digits.
For this feature to work, a CAS signalling class with the template to process ANI/DNIS delimiters has to be defined. This creates a signalling class structure which can be referred to by its name. The name argument must match the name configured in the signaling-class cas command.
Examples
The following example defines a CAS signalling class with the template to process ANI/DNIS delimiters on channel 1:
Router(config)# signaling-class cas testRouter(config-sig-class)# profile incoming S<*a<*d<*nRouter(config)# controller T1 1/0/1Router(config-controller)# cas-custom 1Router(config-ctrl-cas)# class testRelated Commands

Execution of the clear spe command causes the configured firmware to be downloaded to the specified SPE or the range of SPEs and causes power-on self-test (POST) to be executed. This command can be executed regardless of the state of the SPEs.
Caution
This command downloads configured SPEs with firmware as configured. Unconfigured SPEs download with the default firmware, which is the bundled version. To configure and mange the downloading of firmware without abruptly terminating SPEs, use the firmware location or firmware upgrade commands as appropriate.
Examples
The following example clears SPEs when the clear spe command is entered on the Cisco AS5400 with NextPort DFC. This example performs a coldstart on slot 1, SPE 1.

copy modem
To copy modem firmware to integrated modems in an access server, use the copy modem command in EXEC mode.
copy {flash | tftp | rcp} modem
Syntax Description
Command Modes
EXEC
Command History
Usage Guidelines
Note
The Microcom V.34 modems and Cisco AS5200 V.110 terminal adapter will continue to use the copy modem command. On bootup, because these modems do not require download, the command displays the location of the firmware as "feature_card_flash."After you enable this command, you are asked to provide the download destination (a slot/port or all), the remote host name, and the path leading to the source modem firmware.
If a modem that you want to upgrade is busy with a call when the copy modem command is enabled, the upgrade for that modem yields until the active call is dropped. All other idle modems in the upgrade range proceed with the downloading operation.
Examples
The following example copies the modem firmware file called modem_upgrade from the TFTP server called Modem_Server to modem 2/0, which is installed in a Cisco AS5200 access server:

corlist incoming
To specify the class of restrictions (COR) list to be used when a specified dial peer acts as the incoming dial peer, use the corlist incoming command in dial-peer configuration mode. To clear the previously defined incoming COR list in preparation for redefining the incoming COR list, use the no form of this command.
corlist incoming cor-list-name
no corlist incoming cor-list-name
Syntax Description
cor-list-name
Name of the dial peer COR list that defines the capabilities that the specified dial peer has when it is used as an incoming dial peer.
Defaults
No default behavior or values.
Command Modes
Dial-peer configuration
Command History
Usage Guidelines
The dial-peer cor list and member commands define a set of capabilities (a COR list). These lists are used in dial peers to indicate the capability set that a dial peer has when it is used as an incoming dial peer (the corlist incoming command) or to indicate the capability set that is required for an incoming dial peer to make an outgoing call through the dial peer (the corlist outgoing command). For example, if dial peer 100 is the incoming dial peer and its incoming COR list name is list_100, dial peer 200 has list_200 as the outgoing COR list name. If list_100 does not include all the members of list_200 (that is, if list_100 is not a superset of list_200), it is not possible to have a call from dial peer 100 that uses dial peer 200 as the outgoing dial peer.
Examples
In the following example, incoming calls from 526.... are blocked from being switched to outgoing calls to 1900.... because the COR list for the incoming dial peer (list2) is not a superset of the COR list for the outgoing dial peer (list1):
