OL-4306-03
Purpose
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.
The maximum number of time slots available in
Note
a T1 DS0 group is 24. The maximum number of
time slots available in an E1 DS0 group is 32.
You can configure a maximum of 8 time slots in
Note
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.
Configures additional DS0 groups on the T1/E1 interface
to the PBX.
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.
(FXO only) If this voice port supports rotary pulse
dialing, changes the transmit dial type to pulse. The
default is dtmf.
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.
Activates the voice port. You should activate only the
voice ports that you plan to use.
Configures any required digital voice ports.
