DDTs Issue Description
CSCds66369 Title: VISM telnet sessions lock, unable to cc to card until reset.
Description: The VISM card allows up to two sessions. Both of these sessions have
become locked, which prevents the user from being able to use the cc command to
access the card. This condition has been reported twice and is not reproducible in the
lab.
Workaround: Reset the card.
CSCdt62553 Title: XRBK/CO4 does not work with subcell muxing enabled for some calls.
Description: Start calls on 48 endpoints with ground start CAS variant and subcell
muxing enabled. Calls were Inter-VISM and Intra-MGX. Some calls failed with the
“Network COT test failure” error. When running calls with subcell muxing disabled,
it works fine.
Workaround: Disable subcell muxing.
CSCdt85106 Title: G.726-16k, 24k and 40k cannot be configured as Vbdcodec.
Description for VISM 2.2: G.726-16K, G.726-24K, and G.726-40K should not be
configured as Vbdcodec for upspeeding during fax/modem calls. This feature is not
available in VISM Release 2.2.
Workaround: If configuring with VISM CLI commands, do not configure G.726-16K,
G.726-24K, and G.726-40K with cnfvbdcodec. If configuring with SNMP, do not
configure G.726-16K, G.726-24K, and G.726-40K for the vismUpspeedCodec MIB
object.
Description for VISM 2.1: VISM does not allow G.726-16K, G.726-24K, and
G.726-40K to be configured as Vbdcodec for upspeeding during fax/modem calls.
Workaround: None.
CSCdx24153 OAM cells drop in AAL2 trunking with G.711u codec, and VAD disabled in
combination with VISM-PR E1 cards.
CSCdx65569 AAL2 SVC upspeed to clear channel fails when there are more than 24 CIDs.
CSCdx68992 AAL1 SVC-DSP failed to detect tones in AAL1 encapsulation. Mid-call DTMF is not
working for AAL1 SVC grooming solution. Tones are transmitted to the other end
instead of to the call agent.
CSCdx73578 VISM 1:N redundancy on AAL2 SVC call setup fails when reverting to a VISM-PR
card. Calls fail in AAL2 SVC mode after the failed card is returned to primary status.
