OverviewThe ASM-MN-214 is a 19", 4U high, rack-mount, hub for Short Range Modems. The hub accommodates up to 14 cards, and supports more than 20 different types of cards. Any combination of modem cards can be installed. Cards can be removed or inserted during operation without interference to operation of other cards.Operating over 2-wire, 4-wire or fiber optic, baseband modems support data rates from 300 bps to 2.048 Mbps. ASM-MN-214 provides a cost effective and reliable concentration point for multiple baseband links supporting last mile or campus applications.ASM-MN-214 can be powered from either AC or DC power sources, or from both. Each power supply supports a full rack of cards, regardless of the type. The hub accommodates two separate power supplies that back up each other in case of failure. Each power supply can be replaced during operation without affecting the operation of other modems (hot swapping).The ASM-MN-214 rear panel consists of fourteen 5-screw, snap-type terminal blocks and fourteen 25-pin, D-type connectors (one terminal block and one DB-25 connector per card).Modems with X.21 or V.35 interface require an external mechanical adapter. CIA/X.21 can be ordered for converting two adjacent DB-25 connectors to two X.21 15-pin connectors, CIA/V.35 for converting one DB-25 connector to a V.35 34-pin connector.
