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.
