Introduction
he Telenetics RM16M Universal Data Shelf™ is a heavy-gauge
steel-plated modem rack chassis. It measures 7 inches high and
10.75 inches deep, and mounts in a standard 19- or 23-inch rack.
The Data Shelf comes in two versions: AC (RM16M ACV-R) and DC
(RM16M DCV-R). This Guide covers both versions.
Overview
The Telenetics RM16M Universal Data Shelf has slots that accept 16:
v
Modems
v
Multiplexers
v
Digital Data Service (DDS) units
v
Dial backup units
v
Automatic calling units
All of these devices are plug-in printed circuit (PC) cards that slide
into the front of the Data Shelf. The cards can be mixed in any way
within the Data Shelf. Each card has been independently tested and
meets Part 68, FCC rules and regulations.
Power, Data Terminal Equipment (DTE), and communication-line
connections are made at the back panel of the Data Shelf (see “Back
Panel Interface Connectors” on page 9). This allows PC cards to be
installed or replaced, without disturbing the cable connections at the
back
The AC version of the Data Shelf accepts a single power module that
occupies two slots, while the DC version accepts two power modules
that occupy one slot each. The power modules power all the PC cards
