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 MG 1000S. The card is not supported in the MG 1000S Expansion. Up to four digital trunk cards are supported in each MG 1000S.

IMPORTANT!

Each MG 1000S that has a digital trunk must have a clock controller

clocked to an external reference clock.

Note: Clocking slips can occur between MG 1000S systems that are clocked from different Central Offices (COs), if the COs are not synchronized. The slips can degrade voice quality.
