Release Notes for Cisco Voice Interworking Service Module Release 3.0(0)
Part Number OL-2523-01 Rev. B0, January 9, 2004
Important Notes
VISM Redundancy
Table 5 lists the support level for 1:N Service Module Redundancy (N = 1 through 11).
Note You can use a VISM-PR card as a redundant card for a VISM card, but a VISM card cannot be used
as a redundant card for a VISM-PR card. The PXM45 does not provide redundancy support for VISM
cards.
VISM/VISM-PR cards support bulk distribution using the SRM-3T3 and SRM-E (OC3) cards. In a
redundancy configuration VISM/VISM-PR cards in bulk distribution mode do not require any
backcards.
VISM Call Rate
Software Release 3.0(0) for VISM/VISM-PR handles at least 10 CAS, SS7, or PRI calls per second per
VISM card.
Compatibility
Table 6 lists VISM software interoperability with MGX 8850, MGX 8250, and MGX 8230 platform
software.
