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.
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.
IMPORTANT!
Each MG 1000S that has a digital trunk must have a clock controller
clocked to an external reference clock.
