Onhook Detection
—Enables or disables on-hook detection. When you enable
on-hook detection, bandwidth is automatically reallocated based on detection of
an on-hook condition, as specified by the signaling type.
Signaling Type
—The signaling application type:
No
Signaling
,
E&M/PLAR
,
FXO-LoopStart
,
FXS-LoopStart
, or
FXO-GroundStart
for DSX-1 CBR;
R2
for E1 CBR.
You can only modify this field in structured voice mode. In this mode, you can
select any signaling application type except
No
Signaling
. If you try to set the
Signaling
Type
to
No
Signaling
in structured voice mode, you will get an error. In
structured/unstructured data modes, the
Signaling
Type
defaults to
No
Signaling
and cannot be modified. Configured under
Manage Card
. Select
E&M/PLAR
to
configure for dynamic bandwidth allocation (DBA) over ISDN PRI.
DS0 Channels
—The associated DSOs which have been assigned to the specified
ATM VC connection. All available DSO channels are automatically allocated in
unstructured mode. In structured mode, the DSO channels are bit-coded, with
each bit representing one DSO channel. You can assign DSO channels in
structured mode only. Channel conflicts within a T1/E1 port interface will result in
an error.
Configuring CBR Virtual Circuits for DBA
The PathBuilder S700 supports two
types of dynamic bandwidth allocation (DBA): structured voice DBA and structured
data DBA. For details about how DBA works, see “DS0 Signaling and Dynamic
Bandwidth Allocation” in Chapter 4.
In structured voice DBA, the CBR software reads the stored signaling bits and
releases bandwidth when it detects an on-hook (idle) condition. To configure a
CBR virtual circuit for structured voice DBA, follow these basic steps:
1
Configure the CBR Port as follows:
n
Set the CBR
Port Mode
to
Structured Voice
. See “Configuring DSX-1 CBR or E1
CBR Modules” earlier in this chapter for details about setting CBR port
parameters.
2
Configure the virtual circuit as follows:
n
Set the
Mode
to
DBA
.
n
Set the
Payload Size/Type
to
Voice
.
n
Set
Onhook Detection
to
Enabled
.
n
Set the
Signaling Type
to
E&M/PLAR
,
In structured data DBA, the CBR software reads the DSO payload bytes and
releases bandwidth when it detects an on-hook (idle) condition. To configure a
CBR virtual circuit for structured data DBA, follow these basic steps:
1
Configure the CBR port as follows:
n
Set the
Port Mode
to
Structured Data
. See “Configuring DSX-1 CBR or E1 CBR
Modules” earlier in this chapter for details about setting CBR port parameters.
n
Set the
DBA Bits Mask
to mask off bits that you do not want to include in the
idle code.
2
Configure the virtual circuit as follows:
n
Set the
Mode
to
DBA
.
n
Set the
Payload Size/Type
to
Voice
.
n
Set
Onhook Detection
to
Enabled
.
