are not included in this table since they are mounted on the NTAK09
DTI/PRI circuit card and not on a shelf.

NTAK93 D-channel Handler Interface (DCHI) daughterboard
The NTAK93 DCHI daughterboard interfaces with the system Central
Processing Unit (CPU) and mounts on the NTAK09 DTI/PRI circuit card
for PRI or ISL shared mode applications. The DCHI is responsible for
performing the Q.921 layer 2 protocol information. It transfers layer 3
signaling information between two adjacent network switches.
The NTAK93 DCH daughterboard, when installed on the NTAK09 circuit
card, is addressed in the same slot as the NTAK09. The NTAK93 can use
SDI I/O addresses 0 to 79 and port 1.
A minimum of one NTAK93 is required for each PRI link. If more than one
PRI link connects to the same end location, a single DCHI circuit card can
support up to a maximum of sixteen PRI connections for the Small System.
