Channelized E1 and Channelized T1 Setup Commands
This chapter describes commands needed to configure channelized E1 and channelized T1 for the following:
•
ISDN PRI on any platform that supports Primary Rate Interface
•
Robbed bit (in-band) signaling for analog calls over digital T1 lines
•
Channel-associated (out-of-band) signaling over digital E1 lines on the AS5200/AS5300 access servers
In Cisco IOS Release 11.3, all commands supported on the Cisco 7500 series are also supported on the Cisco 7000 series.
autodetect encapsulation
To enable automatic detection of the encapsulation types in operation over a point-to-point link to a specified serial or ISDN interface, use the autodetect encapsulation interface configuration command. To disable automatic, dynamic detection of the encapsulation types in operation on a link, use the no form of this command.
autodetect encapsulation encapsulation-type
no autodetect encapsulation
Syntax Description
encapsulation-type
|
One or both of the encapsulation keywords v120 and ppp.
|
Default
Disabled
Command Mode
Interface configuration
Usage Guidelines
This command first appeared in Release 11.2.
At least one encapsulation type is required in the command, but you can specify additional encapsulation types.
Use this command to enable the specified serial or ISDN interface to accept calls and dynamically change the encapsulation in effect on the interface when the remote device does not signal the call type. For example, if an ISDN call does not identify the call type in the Lower Layer Compatibility fields and is using an encapsulation that is different from the one configured on the interface, the interface can change its encapsulation type dynamically.
This command enables interoperation with ISDN terminal adapters that use V.120 encapsulation but do not signal V.120 in the call setup message. An ISDN interface that by default answers a call as synchronous serial with PPP encapsulation can change its encapsulation and answer such calls.
Automatic detection is attempted for the first 10 seconds after the link is established or the first five packets exchanged over the link, whichever is first.

cas-custom
To customize E1 R2 signaling parameters for a particular E1 channel group on a channelized E1 line, use the cas-custom controller configuration command. Use the no form of this command to disable the signaling customization.
cas-custom channel
no cas-custom channel
Syntax Description
channel
|
Specifies a single channel group number, which can be between 0 and 30. This channel group number must match the channel number specified in the cas-group command.
|
Default
No customized signaling parameters are set. If you do not specify a country name using the country name command, which is described in , ITU is the selected default signal.
Command Mode
Controller configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.2 P.
The customization parameters set by the cas-custom channel command are applied to the same channel group number used in the cas-group channel timeslots range type signal command. These channel group numbers must match. Otherwise, the customized features specified by the cas-custom command will not be applied to the cas-group command's configuration. The signaling customization will not take effect. See Example 1.
However, you will not need to configure or set more than one channel group number per E1 line in most cases. Though rarely used, it is possible to split a single E1 (timeslots 1 to 31) into two groups (for example, 1 to 15 on group 1 and timeslots 17 to 31 in group 2).
Cisco strongly recommends that you use the use-defaults option when specifying a particular country type. See the country name command in . This additional keyword ensures that all the local country settings are correctly enabled. For example, issue the country greece use-defaults command. If the use-defaults option is not specified, generic ITU will be the default setting for all countries. See Example 2.
You can configure the system to deviate from a country's default settings as defined by Cisco. To do this, choose from the following list of commands described in : ani-digits min number max number, answer-signal {group-a | group-b} number, caller-digits number, category number, dnis-digits min number max number, invert-abcd, ka number, kd number, metering, nc-congestion, and unused-abcd value. To return a country back to its country specific default settings, issue the country name use-defaults command. To return a country back to the ITU standard, issue the default country name use-defaults command. See Example 3 and Example 4.
Note
Only integrated MICA modems support E1 R2 signaling on Cisco access servers.
shows a list of command options in cas-custom mode, which is used to customize R2 signaling settings. Some switches require you to fine tune your R2 settings. Do not tamper with these commands unless you understand exactly how your switch will be affected.
Table 45 Available Commands in Cas-Custom Mode
Command
|
Purpose
|
ani-digits min number max number
|
Requested number of ANI digits for each call. All calls that do not match the minimum and maximum settings that you specify will be dropped. The minimum number of collected digits is set by min number. Replace the number variable with a value between 0 and 64. The maximum number of collected digits is set by max number. Replace the number variable with a value between 5 and 64. By default, ANI digits are not collected, which is the ITU standard.
|
answer-signal {group-a | group-b} number
|
Answer signal to be used. You can specify the group A signal or the group B signal. The signal number can be 1 to 15. Default is group-b 6, which is the ITU default.
|
caller-digits number
|
Specifies the number of digits the access server needs to collect before it requests ANI or CallerID information. The digits can be from 1 to 10. Default is 1, which is the ITU default.
|
category number
|
Specifies the category type of the incoming call, which is mapped to a group signal number. Signal numbers from 1 to 15 are available. Default is 1, which is the ITU default.
|
country name use-defaults
|
Specifies the local country, regional, and some corporation settings for R2 signaling. Replace the name variable with one of the following supported country names. Cisco strongly recommends that you include the use-defaults option, which enables the default settings for a specific country. Default country setting is ITU.
• argentina use-defaults
• australia use-defaults
• brazil use-defaults
• china use-defaults
• columbia use-defaults
• costarica use-defaults

• guatemala use-defaults
• hongkong-china use-defaults
The Hong Kong option uses the China variant.
|
| |
• indonesia use-defaults
• israel use-defaults
• itu
ITU is the signaling default. ITU provides support for the following list of countries: Denmark, Finland, Germany, Russia (ITU variant), Hong Kong (ITU variant), and South Africa (ITU variant).
The expression "ITU variant" means that there are multiple R2 signaling types deployed in the specified country, but Cisco supports the ITU variant.
• korea use-defaults
• malaysia use-defaults
• newzealand use-defaults
|
| |
• paraguay use-defaults
• peru use-defaults

• venezuela use-defaults
• vietnam use-defaults
|
default
|
Sets a command to its default setting.
|
dnis-digits min number max number
|
Requested number of DNIS digits for each call. All calls that do not match the minimum and maximum settings that you specify will be dropped. The minimum number of collected digits is set by min number. Replace the number variable with a value between 0 and 64. The maximum number of collected digits is set by max number. Replace the number variable with a value between 5 and 64. By default, DNIS digits are not collected, which is the ITU standard.
|
exit
|
Takes you out of cas custom mode.
|
invert-abcd
|
Inverts the ABCD bits before tx and after rx. This feature is disabled by default, which is the ITU default.
|
ka number
|
Specifies the KA signal code. You can choose 1 to 15. Default is 0, which is the ITU default.
|
kd number
|
Specifies the KD signal code. You can choose 1 to 15. Default is 0, which is the ITU default.
|
metering
|
Specifies sending a metering pulse when the access server is making an outgoing call. Metering is turned off by default, which is the ITU default.
|
nc-congestion
|
Specifies the noncompelled congestion signal. This signal is sent to the central office when the access server is congested and cannot accept the call. The default is B4, which is the ITU default.
|
no
|
Negates a command or sets its defaults.
|
request-category
|
DNIS digits to be collected before requesting category. A category specifies different priority levels for different calls within R2, such as data calls verses voice calls. This information is primarily used for the switches that forward the calls to the NAS.
For example, India needs the category requested after the first DNIS digit.
|
unused-abcd value
|
Specifies unused ABCD bit values, which can have a 0 or 1 bit value. This feature is disabled by default, which is the ITU default.
|
Example 1
The following example displays the available signaling parameters after you enter cas-custom mode. Notice that the same channel group 1 is specified in the cas-group command and the cas-custom command.
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z
router(config)# controller e1 1
router(config-controller) cas-group 1 timeslots 1-31 type r2-digital r2-compelled
router(config-controller) cas-custom 1
router(config-ctrl-cas)# ?
ani-digits Expected number of ANI digits
answer-signal Answer signal to be used
caller-digits Digits to be collected before requesting CallerID
default Set a command to its defaults
dnis-digits Expected number of DNIS digits
exit Exit from cas custom mode
invert-abcd invert the ABCD bits before tx and after rx
metering R2 network is sending metering signal
nc-congestion Non Compelled Congestion signal
no Negate a command or set its defaults
request-category DNIS digits to be collected before requesting category
unused-abcd Unused ABCD bit values
Example 2
You can localize your R2 configuration for a specific country. Don't forget to include the use-defaults option as described in . For example, use the country argentina use-defaults command for a R2 scenario in Argentina.
router(config-ctrl-cas)# country ?
hongkong-china Hong Kong (China variant)
southafrica-panaftel South Africa Panaftel
router(config-ctrl-cas)# country argentina ?
use-defaults Use Country defaults
router(config-ctrl-cas)# country argentina use-defaults
Example 3
The following example customizes the signaling for channel group 1. The configuration collects 3 digits before it requests ANI information for analog calls received on a Cisco AS5300 in Argentina.
router(config-controller)# cas-custom 1
router(config-ctrl-cas)# country argentina use-defaults
router(config-ctrl-cas)# caller-digits 3
router(config-controller)# ^z
Example 4
Because cas-custom mode gives you the flexibility to customize R2 parameters, the margin for user error increases. Therefore, the Cisco IOS software enables you to return a country back to its default R2 settings using the use-defaults option. The following example begins by bringing up Argentina's default settings, changing a few customization parameters, then returning the Argentina R2 setting back to its original state.
router(config-ctrl-cas)# country argentina use-defaults
router(config-ctrl-cas)# caller-digits 3
router(config-ctrl-cas)# unused-abcd 1
router(config-ctrl-cas)# metering
router(config-ctrl-cas)# country argentina use-defaults

Syntax Description
channel
|
Specifies a single channel group number. Replace the channel variable with a number between 0 and 30.
|
timeslots range
|
Specifies a timeslot range, which can be from 1 to 31. You can specify a timeslot range (for example, 1-31), individual timeslots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-14, 15, 17-31). The 16th time slot is reserved for out-of-band signaling.
|
type signal
|
Specifies the type of channel associated signaling. Configure the signal type that your central office uses. Replace the signal variable with one of the following signal types:
• e&m-fgb [dtmf [dnis] | mf [dnis]]—Specifies ear and mouth channel signaling with feature group B support, which includes the wink start protocol. The optional signal tones are DTMF and MF with the option of provisioning DNIS.
• e&m-fgd—Specifies ear and mouth channel signaling with feature group D support, which includes the wink start protocol.
• e&m-immediate-start—Specifies ear and mouth channel signaling with immediate start support.

The following descriptions are provided for the previous R1 and R2 syntax bullets:
r1-modified ani-dnis—Indicates R1 signaling will collect ani and dnis information.
r1-modified dnis—Indicates R1 signaling will collect only dnis information.
r2-analog—Specifies R2 ITU Q411 analog line signaling, which reflects the on/off switching of a tone in frequency-division multiplexing circuits (before TDM circuits were created). The tone is used for line signaling.
r2-digital—Specifies R2 ITU Q421 digital line signaling, which is the most common signaling configuration. The A and B bits are used for line signaling.
r2-pulse—Specifies R2 ITU supplement 7 pulse line signaling, which is a transmitted pulse that indicates a change in the line state.
dtmf—Specifies the DTMF tone signaling.
r2-compelled [ani]—Specifies R2 compelled register signaling. You can also specify provisioning the ANI addr option.
r2-non-compelled [ani]—Specifies R2 noncompelled register signaling.
r2-semi-compelled [ani]—Specifies R2 semicompelled register signaling.
|
Default
For ISDN PRI, the cas-group command is disabled.
If the channelized E1 is not configured as a PRI, the default value for line signaling is e&m-fgb and the default value for tone signaling is DTMF.
The R1 signaling default is ani-dnis.
R2 signaling types have DNIS turned on by default.
Command Mode
Controller configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.2 P.
The R1 options first appeared in Cisco IOS Release 11.3 P.
The R2 options first appeared in Cisco IOS Release 11.3 T.
Use this command to configure support for incoming and outgoing call signals (such as on-hook and off-hook) on each E1 controller.
If you specify the timeslot range 1-31, the system software automatically uses the 16th timeslot to transmit the channel associated signaling.
The signaling you configure on the access server must match the signaling used by the central office. For example if the central office switch is forwarding R2 analog signaling to a Cisco AS5300, then the access server's E1 controller must also be configured for R2 analog signaling (r2-analog).
All R2 signaling options have DNIS support turned on by default. If you enable the ani option, the collection of DNIS information is still performed. Specifying the ani option does not disable DNIS. DNIS is the number being called. ANI is the caller's number. For example, if you are configuring router A to call router B, then the DNIS number is router B, the ANI number is router A. ANI is very similar to Caller ID.
To customize the R2 signaling parameters, refer to the cas-custom controller configuration command. When you enable the cas-group command, the cas-custom command is automatically setup to be polled for configuration information. However, unless you enable or turn on specific features with the cas-custom command, the cas-custom feature has an empty set of signaling parameters.
Note
Only integrated MICA modems support E1 R2 signaling on Cisco access servers.
DNIS is automatically collected for modem pools and R2 tone signaling. You do not need to specify the collection of DNIS information with the cas-group command. However, if you are using non-R2 tone signaling, the system must be manually configured to collect DNIS information. For non-R2 cas signaling, DNIS collection is done only for E&M-fgb.
Examples
In most cases, you will configure the same channel associated signaling on each E1 controller. The following examples configure signaling and customized parameters on controller E1 2 using the cas-group and cas-custom controller configuration commands. The actual channel associated signaling is configured on the 16th timeslot, which is the reason why this timeslot does not come up in the following output.

If the channelized T1 is not configured as a PRI, the default value for line signaling is e&m-fgb and the default value for tone signaling is DTMF.
The R1 signalling default value is ani-dnis.
Command Mode
Controller configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.2.
The service, data, and voice signaling options first appeared in Cisco IOS Release 11.3 T.
The R1 options first appeared in Cisco IOS Release 11.3 P.
Use the cas-group command to configure T1 controllers with different types of robbed bit signaling, such as on-hook and off-hook for E&M feature group B (e&m-fgb).
If you want to collect DNIS information on a T1 controller, you must manually configure it on the access server. DNIS collection is performed only for E&M-fgb. To collect DTMF DNIS for E&M-fgb under a controller T1 configuration, issue the cas-group 0 timeslots 1-24 type e&m-fgb dtmf dnis command. To collect MF DNIS for E&M-fgb, issue the cas-group 0 timeslots 1-24 type e&m-fgb mf dnis command.
Examples
The following example configures all 24 channels with ear and mouth robbed bit signaling with feature group B support:
router(config)# controller T1 0
router(config-controller)# cas-group 1 timeslots 1-24 type e&m-fgb

The following example configures the required signaling to support modem pooling and the digital number identification service (DNIS) over channelized T1 lines on a Cisco AS5300. The only supported signaling and tone types for modem pooling over CT1 RBS are E&M feature group B, DTMF tones, and MF tones. By configuring DNIS as part of the cas-group command, the system can collect DNIS digits for incoming calls, which can be redirected to specific modem pools setup for different customers or services. Additionally, you must be running MICA modems in the system and have at least 10% of your total modems in the default modem pool. Free modems are needed in the default pool to detect the incoming called number or DNIS before handing the call off to the appropriate modem pool. Therefore, two modems are actually needed to handle each incoming call.
Note
Make sure that your switch provides inband address information for incoming analog calls before you enable this feature.
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

The next example configures a Cisco AS5200 to accept switched 56K digital calls on both of its T1 controllers:
router(config)# controller T1 0
router(config-controller)# cas-group 1 timeslots 1-24 type e&m-fgb service data
router(config-controller)# framing esf
router(config-controller)# clock source line secondary
router(config-controller)# linecode b8zs
router(config-controller)# exit
router(config)# controller T1 1
router(config-controller)# cas-group 1 timeslots 1-24 type e&m-fgb service data
router(config-controller)# framing esf
router(config-controller)# clock source line primary
router(config-controller)# linecode b8zs
router(config-controller)# exit
router(config)# copy running-config startup-config
The next example configures switched 56K digital services and analog modem services on one controller. Each service is assigned its own range of timeslots. Switched 56K calls are assigned to timeslots 1 through 15. Analog modem calls are assigned to timeslots 16 through 24. However, you must use different channel group numbers in each cas-group command entry.
router(config)# controller T1 0
router(config-controller)# cas-group 0 timeslots 1-15 type e&m-fgb service data
router(config-controller)# cas-group 1 timeslots 16-24 type e&m-fgb service voice
router(config-controller)# framing esf
router(config-controller)# clock source line secondary
router(config-controller)# linecode b8zs
router(config-controller)# exit
The following example would configure R1 Signaling on a Cisco AS5200 (T1 interface) and
specify the collection of both ani and dnis information:
5200(config-controller)# cas-group 1 timeslots 1-24 type r1-modified ani-dnis
channel-group
Use the channel-group controller configuration command to define the timeslots that belong to each T1 or E1 circuit. Use the no form of this command to clear the timeslots for the T1 or E1 circuit.
channel-group number timeslots range [speed {48 | 56 | 64}]
no channel-group [number timeslots range]
Syntax Description
number
|
Channel-group number. When configuring a T1 data line, channel-group numbers can be values from 0 to 23. When configuring an E1 data line, channel-group numbers can be values from 0 to 30.
|
timeslots range
|
One or more timeslots or ranges of timeslots belonging to the channel group. The first timeslot is numbered 1. For a T1 controller, the timeslot range is from 1 to 24. For an E1 controller, the timeslot range is from 1 to 31.
|
speed {48 | 56 | 64}
|
(Optional) Line speed (in kilobits per second) of the T1 or E1 link.
|
Default
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 Mode
Controller configuration
Usage Guidelines
This command first appeared in Release 11.3MA.
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 timeslot range must match the timeslots assigned to the channel group. The service provider defines the timeslots that comprise a channel group.
On the Cisco MC3810 access concentrator, only one channel group can be configured on a controller.
Example
The following example defines three channel groups. Channel-group 0 consists of a single timeslot, channel-group 8 consists of 7 timeslots and runs at a speed of 64 kbps per timeslot, and channel-group 12 consists of a single timeslot.
channel-group 0 timeslots 1
channel-group 8 timeslots 5,7,12-15,20 speed 64
channel-group 12 timeslots 2
