Introduction
This section describes the two Lineside T1 interface cards:
•
NT5D11 – applicable for Large Systems only
•
NT5D14 – applicable for Small Systems only
Note: Unless otherwise stated, the information in this section
applies to both the NT5D11 and NT5D14 Lineside T1 interface cards.
The NT5D11 Lineside T1 Interface card is an intelligent 24-channel digital
line card that is used to connect the switch to T1-compatible terminal
equipment on the lineside. The T1-compatible terminal equipment includes
voice mail systems, channel banks containing FXS cards, and key systems
such as the Nortel Norstar. The Lineside T1 card differs from trunk T1 cards
in that it supports terminal equipment features such as hookflash, transfer,
hold, and conference.
