Dual-card configuration
The dual-card configuration enables a single conference to occur on
two cards and have up to 62 participants depending on access type. In
the dual-card configuration, one card is the primary card, and the other
is the secondary card. Each card can host single-card conferences of
three to 32 participants, or a dual-card conference, which occupies
ports on both cards.
Note: There is no need for ICB cards in a dual-card configuration to
reside next to each other in an IPE shelf. Software establishes the
audio connections between the two cards. There is no hardware
connection between the two cards.
Datafill the following tables and command interfaces for dual-card
configuration:
• table LNINV
• table ACDGRP
• table ACDSGRP
• table ACDRTE (requires a new entry)
• table ACDLOGIN
• table DNROUTE
•table OFRT
Figure 20 on page 61 provides an example of the datafill for dual-card
setup.
Note: If single-number access is being used, DN pairs are not
required. Instead configure two single-number access DNs: one for
callers to use to access simple conferences on the primary card and
one for callers to use to access simple conferences on the secondary
card.
