The RM16M shelf is the ideal 16 slot enclosure for all your transmission product requirements. This enclosure features modular, redundant power supplies, multiple backplane configurations and the ability to mount it in either a 19" or a 23" (19" or 23' wide by 7.25" tall by 10" deep) cabinet using a reversible bracket. It supports the following Motorola  transmission products: V.3229, V.3400, V,3600 analog modems, UTA 220 ISDN TA, MR64 DSU/CSU, and FT100 T1-Fract. T1 DSU/CSU.


The Model 1 enclosure is a 115 VAC enclosure featuring a full backplane to support 16 PSTN V.32XX modems. Each slot is equipped with one RJ45 modular jack and one RS 232 DTE (DB25 F) interface.

The Model 2 enclosure. Same as above except the backplane has 2 PSTN 50 pin Mass Termination connectors with 4 port wire wrap in place of the RJ45 connections.

Part # 62005202

The Model 3 enclosure is our modular enclosure for maximum flexibility. This 115 VAC enclosure ships with blank segments instead of a backplane enabling "mix and match" of modems and DSU/CSU's in the same enclosure. DSU/CSU cards (MR64 and FT100) ship with a single slot backplane, modem back-planes are ordered separately.

Part # 62005203

Other shelves include 230 VAC and -48VDC versions of above, as well as lease line and dial back-up via dual modular or dual mass termination back-planes. The following page contains the currently available models as well as options and accessories.
