Introduction
The NTAK10 2.0 Mb DTI card is a digital trunk card that provides an
IPE-compatible 2.0 Mb DTI interface. This circuit card includes an on-board
clock controller that can be manually switched in or out of service.
You can install this card in slots 1 through 4 in the Media Gateway. The card
is not supported in the Media Gateway Expansion. Up to four digital trunk
cards are supported in each Media Gateway.
ATTENTION
IMPORTANT!
Each Media Gateway that has a digital trunk must have a clock controller clocked
to an external reference clock.
Note: Clocking slips can occur between systems that are clocked from
different Central Offices (COs), if the COs are not synchronized. The
slips can degrade voice quality.
The NTAK10, which can be located in the main cabinet and IP expansion
cabinets, provides an IPE-compatible 2.0 Mb DTI interface for the Option
11C system. This circuit card includes on-board clock controller circuitry
that can be manually switched in or out of service.
