Dsp Card Slot Id
Default:
0
Range: Chassis
dependent
Format: Numeric
Specifies the slot number of the DSP2
x
Voice
Server module from which the software DSP
Resource Manager selects DSPs to reroute and
reconnect DSP-processed connections, in the
event of active DSP resource failure. If you
selected
Manual
in the Dsp Select Type field, you
must specify the DSP2
x
Voice Server module slot
number in the Dsp Card Slot Id field from which
you want the DSP Resource Manager to select
replacement DSPs. If no DSP resource is available
on the DSP2
x
module in the specified slot, the
connection is rejected. If you selected
Auto-
matic
in the Dsp Select Type field
,
the Dsp Card
Slot Id field is not displayed.
Num of DSP Chnl
Default:
0
Range: 0–384
Format: Numeric
Specifies the number of DS0s that can be
reserved as DSP channels. If the IWF Type is
Packet-pipe
, the bandwidth configured by you
for the trunk calculates how many DS0s fit into
the trunk. For example, the DS0 line rate is
approximately 171 cps. If you want 200 cps, the
bw actually alloocated is 200/171, or 1.16 DS0s.
The CAC reserves the DS0 resource when the
first connection is made on the trunk. If the value
is left at the default 0, the number of reserved
DS0s is best-effort.
Note:
If you have selected
Packet-pipe
in the
Dsp Iwf Type field, how bandwidth is assigned to
the DSP channels also depends on what type of
CBR or VBR you select in the Service Type field
(see the Dsp Iwf Type and Service Type fields for
more details).

Default:
0
Range: N/A
Format: numeric
Displays the last release cause code. The cause
code indicates a reason why the last attempted
call was released.
[Last Rls Diag]
(display only)
Default:
N/A
Range: N/A
Format: predefined
alphanumeric
Displays the last release diagnosis. The value in
this field explains how the connection was
released and reported by the far end of the con-
nection.
[Retry Counter]
(display only)
Default:
N/A
Range: N/A
Format: numeric
Displays how many attempts to establish the con-
nection have failed. The counter is reset when-
ever a connection is successfully established or
the signaling side of the connection is restarted.
