1.3.1 The MTAS Shelf

The MTAS-192 shelf is 3 Rack Units in height and can be rack-mounted in either a 19”

or 23” ANSI- and ETSI-dimensioned equipment rack or cabinet using universal

mounting flanges. The actual dimensions of the shelf are 5.22″ high by 17.3″ wide

(without the mounting flanges) by 10.5″ deep. Refer to Figure 3.

MTAS-192 shelf contains nine card slots. The first eight slots (#1-8, labeled from left to

right) are reserved for line cards, each providing xDSL splitter and/or metallic test

access to 24 2-wire lines. Therefore, one MTAS-192 provides MTA to 192 2-wire lines.

The ninth slot is reserved for the Control Card.
