Chapter 7 Configuring ATM Trunking
Adding a Bearer VCC Identifier
Dsp Iwf Type
Default: None
Range: N/A
Format: Predefined
Specifies the Interworking function type on assigning
AAL2 connections to compatible DSP chips on the DSP2C
through DSP2F Voice Server modules.
None
Allows the assignment of standard AAL2 connections to
DSP chips on the DSP2C Voice Server module that are
configured as AlgoSet1 through AlgoSet3, and on the
DSP2E/F as AlgoSet1 and AlgoSet6. This parameter
allows the mixture of pure voice (CE-to-ATM) with data
(VBR-to-ATM) in the same AAL2 trunk group, such as is
used in the European LES trunking standard V.5.2. This
parameter supports applicable connection types of previ-
ous PSAX system software releases.
Packet-pipe
Allows the assignment of standard AAL2 connections to
DSP chips on the DSP2E/F modules that are configured
as AlgoSet7. This parameter will not allow the mixture
of pure voice (CE-to-ATM) with data (VBR-to-ATM) in
the same AAL2 trunk group. This parameter supports
applicable connection types for pure data (VBR-to-ATM)
in wireless applications.
How bandwidth is assigned for this type depends on what
type of CBR or VBR you select in the Service Type field.
Note:
The value Packet-pipe cannot be used with the
DSP2C Voice Server module.
Gsm
Allows the assignment of standard AAL2 connections to
DSP chips on the DSP2E/F modules that are configured
as AlgoSet8. This parameter will not allow the mixture
of pure voice (CE-to-ATM) with data (VBR-to-ATM) in
the same AAL2 trunk group.
Note:
GSM cannot be used on the DSP2C/D Voice
Server modules.
Dsp Select Type
Default: Auto-
matic
Range: N/A
Format: Predefined
Specifies how connections to DSP resources are re-routed
and reconnected to other DSP resources in the event of
DSP resource failure (a DSP resource is a single chip on
any DSP2x module). The setting you select in this field
must
match the setting in the Selection Type column on
the Dsp Resource Management Table (after the site-spe-
cific DSP Resource Configuration option), or your con-
nections will
not
be assigned or activate.
Automatic
If a DSP resource fails, connections are rerouted by a soft-
ware DSP resource manager that selects available DSPs
from a chassis-wide pool.
Manual
If a DSP resource fails, the DSP resource manager selects
DSPs from a particular module designated in the Dsp Slot
Id field (configured by you).
