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):
