I/O filter connector
Scenario
The installer forgets to replace the standard IPE
module I/O filter connector with the provided
Voice Gateway Media Card/ITG-specific filter
connector that removes filtering from pairs 23
and 24.
The installer installs the Voice Gateway Media
Card/ITG-specific filter connector on top of the
standard IPE module I/O filter connector.
The installer encounters an IPE module that is
equipped with standard filter connectors molded
onto the backplane I/O ribbon cable assemblies.
The installer does not replace the IPE module
backplane I/O ribbon cable assemblies with
the ones that have interchangeable I/O filter
connectors.
The UTP cabling from the TLAN network
interface to the Layer 2 switch does not meet the
UTP CAT5 termination and impedance uniformity
standards.
Voice Gateway Media Card ELAN and TLAN network interfaces
CS 1000M system
The ELAN and TLAN network interfaces are provided by one of the following:
•
•
The ITG-P 24-port line card uses the NTMF94EA ELAN, TLAN, RS-232
Serial Maintenance I/O interface cable.
The Media Card uses the A0852632 Shielded 50-pin to Serial/ELAN/TLAN
Adapter.
The ELAN network interface supports 10BaseT operation and the TLAN
network interface supports 10/100BaseT operation. To support the
100BaseT operation on Large Systems, the TLAN network interface
requires specialized I/O panel mounting connectors. These replace the
standard connectors provided on the system.

Solution
Correctly install the Voice Gateway Media
Card/ITG-specific filter connector by replacing
the standard IPE Module I/O filter connector.
Correctly install the Voice Gateway Media
Card/ITG-specific filter connector by replacing
the standard IPE Module I/O filter connector.
Order new IPE Module Backplane I/O ribbon
cable assemblies that have interchangeable I/O
filter connectors if it becomes necessary to use
one of the IPE Modules with molded-on I/O filter
connectors.
Always ensure that UTP cabling from the
TLAN network interface to the Layer 2 switch is
CAT5-compliant.
