•
Supported on all codec templates for the H248 protocol.
•
Supports all card types such as T1, E1, OC3, and so on.
•
Supports a maximum eight of bearer pools.
•
Supports minimum zero and a maximum of eight bearer IPs in each pool.
•
VXSM shall support two new packages vpnd and evpnd while creating pdn termination.
•
Pools can be shared across different Virtual Media Gateways (VMG).
•
The default pool name is networkA.

New Features in Release 5.6.10
For Multiple Bearer IP Pool feature, the following commands were added:
– addBearerPool
Adds bearer pools.
– cnfBearerPool
Configures the bearer pools.
– delBearerPool
Deletes a bearer pool.
– dspBearerPools

Support for Alternative Codec String
Release 5.6.10 introduces support for alternate strings for existing codecs. Presently VXSM supports
only standard codec strings such as PCMU, G.711u, and so on. This feature enables VXSM to use the
alternate strings in addition to the existing standard strings. The following call control protocols support
this feature:
•
H.248
•
MGCP
The feature supports these codec templates:
•
TGW and Wireline: Supports G.711, G.723, G.723.1a, G.726, G.729, G.729A, and Clear Channel.
•
Cable: Supports G.711 and iLBC.
•
TGW2: Supports G.711, G.726, G.729A, iLBC, and Clear Channel.
•
FMC: Supports G.711, G.726, G.729A, AMR-NB, GSM-EFR, and Clear Channel.
For the Support for Alternative Codec String feature, the following commands were added:
– cnfcodecstring
Specifies the alternate codec strings for VXSM.
– dspcodecstring
Displays the alternate codec strings for a specific
adaptation type and codec.
Hold Tone During Warm Transfer
This enhancement introduces a new type of hold tone during a warm transfer. The new tone is played
during the warm transfer period. Only MGCP protocol supports this enhancement.
For the Hold Tone During Warm Transfer feature, the following commands were modified:
– cnfvifccode
Configures a specific country code in a voice interface.
– dspvifccode
Displays country code configured for a specified Voice
Interface.
– dspvifccodes

Firmware Images
Increased Announcement IDs on VXSM
Release 5.6.10 increases the announcement identifiers on the VXSM from 1024 to 9924. Only H.248
protocol supports this enhancement.
For the Increased Announcement IDs on VXSM feature, the following commands were modified:
– cnfannfile
Configures Announcement File.
– dspannfile
Displays the configuration parameters for a specified
announcement file.
– dspannfiles
Displays the configuration parameters for a all the
announcement files.
Ignoring Unsupported Parameters in SDP
Effective this release, when VXSM receives any unsupported parameters in a Session Description
Protocol (SDP) for a codec, it ignores the unsupported attributes and does not consider that particular
codec for negotiation. This prevents VXSM from rejecting the whole SDP. If a single codec is received
in the m-line, and the SDP validation fails, the VXSM does not acknowledge that request. Only H.248
protocol supports this enhancement.
Also note that when VXSM receives multiple SDPs in the local descriptor with the first one with media
type as VIDEO and subsequent one with media type as AUDIO, VXSM will ignore the first SDP and
process the second SDP instead of returning any error, because VXSM does not support media type
VIDEO. This will also apply if a single SDP is received with multiple m lines, with first one with media
type as Video and subsequent one with media type as Audio. Here also, VXSM will ignore the m lines
with media type VIDEO and process the first m line found with media type as AUDIO.
Preference for Codec Negotiation
This enhancement allows a user to specify the codec negotiation preference to either remote or local
code. Only H.248 protocol supports this enhancement.
For Preference for Codec Negotiation feature, the following commands were added:
– cnfCodecNegoPreference
Sets the codec negotiation preference.
– dspCodecNegoPreference
Displays the codec negotiation preference.
Firmware Images
For each VXSM card type (OC-3/STM-1, T1/E1, or T3), two firmware images are available, namely,
Non-CALEA and CALEA. When placing an order, the user must specify whether a Non-CALEA or
CALEA image is required.
Both CALEA and Non-CALEA images supports three Media Gateway Control protocols, namely,
H.248, MGCP, and TGCP. However, VXSM supports only one protocol at a time. The user must choose
between the H.248, MGCP, and TGCP protocols when the image is first loaded from the PXM using the
setrev command.

OL-23364-03
Upgrading from an Earlier VXSM Release
The CALEA image supports LI based on SII architecture for H.248, TGCP and MGCP protocols. The
PktCable CALEA is supported only with MGCP and TGCP protocols.
VXSM supports four different Codec templates; Tandem Gateway (TGW), Tandem Gateway 2, Fixed
Mobile Convergence (FMC), and Cable. The Cable template can be used only in conjunction with TGCP.
Upgrading from an Earlier VXSM Release
VXSM can be gracefully upgraded (configuration is preserved) from VXSM Release 5.5.00 or later.
Note
VXSM supports upgrade of non-CALEA to CALEA firmware. But upgrade from CALEA to
non-CALEA is not supported.
When loading or upgrading a boot or runtime image to a VXSM card, users must observe the following
caution:
Caution
If an H.248 association is active with SrvChgProfile (used in service change message) as BT_TGW in
5.3.x.x release, after graceful upgrade to 5.6.10, the association will continue to use BT_TGW, but new
association(s) cannot be added with SrvChgProfile as BT_TGW.
From the 5.4.00 release onward, the BT_TGW SrvChgProfile is no longer available. All new
associations must be added using either etsi_tgw or CISCO_TGW.
Prior to upgrade, user should confirm that additional termtypes (other than the defaults) have not been
configured for VXSM in H.248.
Warning
Many of the commands involved in loading or upgrading boot and runtime images can take several
minutes to execute completely. If the user resets or otherwise disturbs the VXSM card during a
loading or upgrading process, the card can easily be damaged even to the extent that it must be
returned to the factory for repair.
In particular:
Do not reset VXSM or PXM cards manually or through commands such as resetcd or resetsys
Do not save all MGX configurations with commands such as saveallcnfs.
Do not toggle primary/secondary cards through commands such as switchredcd, delred
Do not change the name of software image before or during the upgrade
Do not change any configuration of active primary card during the upgrade
THE REAPPEARANCE OF THE COMMAND PROMPT AFTER A COMMAND IS ENTERED DOES NOT
INDICATE THAT THE IMAGE LOAD OR UPGRADE HAS BEEN COMPLETED.
After the execution of the burnboot, clrsmcnf, loadrev, or setrev commands, the user must execute
either a dspcds or dsprev command periodically to verify that the state of the VXSM card being loaded
or upgraded is either Active, Standby, or Failed.
ONLY WHEN THE CARD IS DISPLAYED TO BE IN ONE OF THESE STATES IS IT SAFE TO GO TO THE NEXT
STEP.

Feature Clarifications
If the upgrade procedure is interrupted for reasons outside the control of the user (for example, a
power outage), see “Interrupted Procedure Recovery” below for instructions.
Interrupted Procedure Recovery
In the event that a VXSM software upgrade procedure is interrupted (for example, power outage), and
both Primary and Secondary are stuck in 'Failed-U' state, perform the following procedure:
Step 1
Execute the abortrev command:
abortrev <PrimarySlot> <NewImageRevision>
Step 2
If the primary VXSM becomes “Failed/Active” (out of Failed-U/Active”), then execute the resetcd
command
resetcd <PrimarySlot>
Step 3
If the secondary VXSM becomes “Failed/Active” (out of Failed-U/Active”), then execute the resetcd
command:
resetcd <SecondarySlot>
Step 4
Both primary and secondary VXSM cards should now have their original SW image and original DB
Feature Clarifications
Call Rate Performance Support
VXSM OC3 Card supports the following call rates:
•
In MGCP, the maximum CPS supported is 60 (without signaling). If signaling (M3UA/IUA/RUDP)
is configured, then the maximum supported CPS is 50.
•
In H.248, the maximum CPS supported is 85 (without signaling). If signaling (M3UA/IUA) is
configured, then the maximum supported CPS is 50.
Online Diagnostics Feature as Applied to VXSM
The online diagnostics feature as implemented on the PXM45 card is supported on VXSM. When
enabled, using the PXM45 cnfdiag command, this feature performs non-intrusive diagnostics tests that
use four of the VXSM G711 DSP resources.
If the user executes the VXSM dspdspcodecpools command, the resulting display shows the four G711
DSP resources being used (for diagnostics) and subtracts them from the remaining available Codecs (see
example below).

In this example, 175 G711 calls have been established along with four G711 resources used for
diagnostics.
The online diagnostics feature does not reduce the maximum number of 8064 G711 DSP resources
available for calls on the VXSM card. If the number of call requests on the VXSM is sufficiently high,
the online diagnostic feature is disabled automatically and the four Codecs are made available for active
calls.
DSP Resources Under Mixed Codec Conditions
When the same Codec is used to setup calls on the gateway the available DSP resources will be fully
utilized. However when different Codecs are used to setup calls the amount of utilizable DSP resources
may be limited in certain cases due to resource fragmentation.
Fragmentation is said to have occurred when the available capacities on two different DSP resources
have enough available capacity to support a call of a particular Codec type but cannot support that Codec
type individually.
Consider two DSP resources whose available capacity is 1 unit each making the total available capacity
2 units. However a Codec that requires 2 units cannot be supported in the system because the available
capacities have been fragmented across the individual DSP resources.
The DSP allocation algorithm on VXSM does make an attempt to smooth the effects of fragmentation.
Fragmentation can happen because the pattern of future calls cannot be predicted beforehand.
