Chapter 3 Configuring with the Command-Line Interface

Configuring T1/E1 Interfaces

Step 5

ds0-group

ds0-group-number

timeslots

timeslot-list

Example:

Router(config-controller-cas)# ds0-group 1

timeslots 1-4

Creates a DS0 group on the T1/E1 trunk. A DS0 group

can contain from 1 to 24 time slots numbered from 0 to

23 for T1, and 1 to 32 time slots numbered from 0 to 31

for E1.

Note The maximum number of time slots available in

a T1 DS0 group is 24. The maximum number of

time slots available in an E1 DS0 group is 32.

Note You can configure a maximum of 8 time slots in

a DS0 group on the IAD2435 IAD.

When configuring a DS0 group for a T1/E1 line to a

PBX, make sure that the time slot numbers match the

channels on the PBX. Contact the PBX administrator to

determine which channels to use.

Time slots with identical voice-port configuration can be

assigned to one DS0 group.

Time slots with nonidentical voice-port configurations

must be assigned to different DS0 groups.

Note The maximum number of time slots available in

a T1/E1 is 24. The time slots can be assigned to

one DS0 group, or they can be assigned to as

many as 24 DS0 groups within the T1/E1.

Step 6

Repeat Step 3 for each additional DS0 group. After DS0

groups are defined, exit CAS configuration mode.

Configures additional DS0 groups on the T1/E1 interface

to the PBX.

Step 7

voice-port

slot/port ds0-group-no

Example:

Router(config)# voice-port 1:D

Enters voice-port configuration mode, and specifies the

voice port that you want to configure. The logical slot for

these voice ports is the same as for the T1 controller. (See

Step 1). The logical port is 0 to 23 for T1 and 0 to 31 for E1,

corresponding to the DS0 group.

Step 8

dial-type {pulse|dtmf}

Example:

Router(config-voice-port)# dial-type dtmf

(FXO only) If this voice port supports rotary pulse

dialing, changes the transmit dial type to pulse. The

default is dtmf.

Step 9

compand-type {u-law|a-law}

Example:

Router(config-voice-port)# compand-type a-law

Changes the companding, if necessary. The default is

u-law (the North American mu-law ITU-T pulse code

modulation (PCM) encoding standard). Specify a-law to

use the European a-law ITU-T PCM encoding standard.

Step 10

no shutdown

Example:

Router(config-voice-port)# no shutdown

Activates the voice port. You should activate only the

voice ports that you plan to use.

Step 11

Exit voice-port configuration mode and repeat Step 5

through Step 8 for the remaining digital voice ports.

Configures any required digital voice ports.
