Connection ID Attributes for SVCs
The VPI/VCI address range fields allow you to design a VPC VPI or VCC VPI/VCI 
address range to match the capability of the equipment attached to this port. 
1. From the Configure SVC dialog box, select the Connection ID tab (Figure 17-12).
2. Complete the fields in the Connection ID tab, as described in Table 17-7.
IE Sig Override Mask This parameter enables the switch to override the standard 
signaling protocol for specific information elements at this 
logical port. If an IE’s corresponding bit is set, the 
information element is always signaled. If an IE bit is 
cleared, the IE may or may not be sent out, but the decision 
will be based on the standard signaling protocol. 
Select one of the following check boxes, depending on 
how you wish to configure this SVC endpoint:
Called Party — Remote address where the call is 
terminating (egress address).
Calling Party — Remote address where the call is 
initiated (source address).
User-User — Between calling party and called party.

Field Description
Note  – If you are using the Enhanced Channelized IMA IOM in DS3 or STM-1 
mode, and when configured in UNI mode, the default SVC Connection ID Range is 
zero (0) to 255. The corresponding default values for Number of Valid Bits in VCI (6) 
and Number of Valid Bits in VPI (8) are displayed in the ATM tab, as described in 
Table 3-4 on page 3-29. When the Enhanced Channelized IMA IOM in DS3 mode is 
configured in IMA mode, the standard SVC Connection ID Parameters default values 
are used.
