Introduction

The NTAK93 provides the D-channel handler interfaces required by the ISDN PRI trunk.

The DCHI performs D-channel Layer 2 message processing and transfers Layer 3 signaling
information between two adjacent network switches. It is mounted on the NTAK09 1.5 Mb DTI/
PRI card or the NTBK50 2.0 Mb PRI card (installed in the Media Gateway) using standoff
reference pins and connectors. The NTAK93 daughterboard, when mounted on the NTBK50
PRI digital trunk card, is addressed in the same slot as the NTBK50. The NTAK93
daughterboard can use SDI I/O addresses 1 to 15 and port 1.

The NTAK93 provides the following features and functions:

• D-channel interface or DPNSS interface

• Special features included for LAPD implementation at DCH:

- system parameters are service changeable (system parameters are downloaded

from software)

- incoming Layer 3 message validation procedures are implemented in the D-PORT

firmware

- supported message units and information elements can be service changed

- translation of the CCITT message types information elements into a proprietary

coding scheme for faster CPU operation
