Overview

This procedure provides steps for replacing a Quad T1 Framer (QF) card. The Access Navigator

can hold up to eight QF cards, providing a total of 32 DS1 circuits. QF cards are hot-swappable and

can be installed at any time, without interrupting service on other cards, except when the card is

providing a DS1 clock source used for system timing.

Each Quad T1 Framer card contains four DS1 circuits. DS1 circuit numbers are determined by the

QF card slot (see also Figure 16-10):
