Introduction
he Telenetics RM16MUniversal 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:
vModems
vMultiplexers
vDigital Data Service (DDS) units
vDial backup units
vAutomatic 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

in the Data Shelf, converting user-supplied 48 volt DC input to + 15
Vdc, −15 Vdc, and +8.5 Vdc outputs for distribution to the PC cards.
Regulators on the PC cards convert the plus and minus 15 Vdc to plus
and minus 12 Vdc and + 8.5 Vdc to +5 Vdc.
NOTE: If two power modules are installed in the DC version of the
Data Shelf, one powers the Data Shelf while the other acts as a
redundant power source.
Figure 1-1 shows an example of the location and orientation of the
modem cards and power module. For convenience, the front panel of
the Data Shelf is hinged to allow easy access to the modem cards and
power module(s) without disturbing the DTE and communication-line
connections at the back of the Data Shelf.

Back Panel Interface Connectors
All DTE, Telco and power connections are made at the back panel of
the Data Shelf.
The DTE connectors can be:
vIndividual 25-pin connectors one for each PC card (standard)
vTwo 50-pin mass termination connectors (optional)
vWire-wrap pins (optional)
The Telco connectors can be:
vIndividual 8-pin modular jacksone for each PC card (standard)
vTwo 50-pin termination connectors (optional)
vWire-wrap pins (optional)
The telephone-line connectors are identified by the telephone
company Universal Service Ordering Code (USOC) and must be
specified when ordering standard jack arrangements from Telenetics.
The various jack arrangements ensure that the signal level received at
the telephone company central office does not exceed–12 dBm. The
Data Shelf has been registered with the FCC per the requirements of
Part 68 of the FCC rules for:
1. Programmable Mode the local telephone company will install a
resistor internal to the jack (USOC RJ455 or RJ41S).
2. Permissive Mode the individual modem cards are
preprogrammed for a maximum transmit level of –9 dBm (USOC
RJ11C or RJ16X).
Figures 1-3 through 1-5 show examples of Data Shelf back panels.
NOTE: For more information about the power connections, refer
to “Electrical Installation” on page 16.

LocalView DC Shelf Model
The LocalView DC shelf is a special model of the DC version of the
Data Shelf that provides modem system network management.
Figure 1-6 shows the back panel of the LocalView Data Shelf.
LocalView allows devices in a Shelf to be controlled or interrogated
through shared input/output devices.
The system includes a controller that resides in slot 16 of the Shelf and
a modified backplane that uses unused pins on the power connector
to pass data, address, and control information between the controller
and device cards.
LocalView allows a single controller to address up to five shelves.
With these shelves fully populated, a total of 79 device cards can be
addressed either from the LCD on the front of the controller or through
an RS232 port on the rear of the controller. For information, refer to the
LocalView controller card manual.

Installation
his chapter describes how to install the Data Shelf.
Unpacking and Inspecting the
Equipment
Unpack the equipment and compare the contents to the packing list.
Inspect the equipment for any damage that may have occurred in
shipment. If you see any damage or if items are missing, contact
Telenetics. Keep the shipping container and packing material for
future shipment.
Site Preparation
When selecting a location to install the Data Shelf, choose a site that:
vIs clean, well lit, and free from extremes of temperature, humidity,
appreciable shock, and vibration.
vIs within seven feet of a power source that can furnish 48 ±4 Vdc
at 3.5 amps.
vIs within 50 feet of the associated data terminal.
vProvides at least 36 inches of clearance at the front for operating
and maintenance accessibility.

Installation
Page 14
vProvides at least 4 inches at the back of the enclosure for interface
cable clearance and unobstructed airflow.
Side and top clearances for rack-mounted equipment are dictated by
the rack-cabinet provisions, but should allow a free flow of cooling air
(Figure 2-1).
Figure 2-1. Data Shelf Cabinet

Page 15
Installation Procedures
Service personnel should be familiar with the complete installation
procedure before installing the shelf.
Required Tools and Equipment
Special tools or test equipment are not required for installation.
CAUTION: To prevent damage to enclosure components from
overheating, ensure clearances of 1 ¾-inch top and bottom
between mounted enclosures. Make adequate provision for cool
air circulation and exhaust of warm air, such as air intake louvers
in the bottom panel of the Data Shelf cabinet and an adequate
CFM exhaust fan in the top panel of the Data Shelf cabinet.
Mechanical Assembly
The Data Shelf mounts into a standard 19-inch cabinet and requires 7
inches of vertical panel space (see Figure 2-2).
The 19-inch Data Shelf also fits into a 23-inch cabinet. This installation
requires the rack-mounting brackets to be removed and reinstalled in
the reversed position, so the wider tabs are used for mounting to the
cabinet (see Figure 2-3).

Electrical Installation
All power connections are made at the back panel of the Data Shelf.
AC Power (RM16M ACV-R Data Shelf)
Power for the AC version of the Data Shelf (RM16M ACV-R) is
supplied to the power modules through a separate AC power cord.
The power cord is fastened to the back panel with a cable clamp to
prevent it from becoming unattached.
After the power module is installed and fastened to the rear panel,
insert the power cord into the power module socket on the back of the
Data Shelf.
To apply power to the module plug the opposite end of the power
cord into a standard 115VAC grounded wall socket.
DC Power (RM16M DCV-R Data Shelf)
Power for the DC version of the Power Shelf (RM16M DCV-R) is
provided by an incoming power source that connects to TS1, TS2, or
both on the back of the Data Panel (see Figure 2-4). Facing the front of
the Data Shelf, TS1 supplies the power module on the left and TS2
supplies power to the power module on the right.
One power module is sufficient to power all 16 slots. If one power
source is available, it can connect to either terminal strip (TS1 or TS2)
on the back of the Data Shelf, with shunt bars installed to connect
power to the opposite strip (see Figure 2-5). The bars should always
be installed if only one power source is used and must be removed if
two power sources are used.
TS1 and TS2 alarms and chassis ground are connected internally. An
alarm condition exists on the alarm circuit when any operating or
supply voltage is lost on either power supply. By observing which
front panel power LED is out, you can identify the faulty power
supply.

Digital EIA-232 Interface
The 16 EIA-232C or D digital input connectors are labeled and shown
in Figure 2-2. These connectors are either Cannon or Cinch 25-pin D
series, as defined in EIA-232. For a description of the active pin
connectors, refer to Appendix D on page 39.
Table 2-1 shows the EIA-232 levels from the modem.

Telephone Line Interfaces
The Data Shelf is FCC certified for connection to the dial-up Public
Switched Telephone Network (PSTN). The following sections describe
the standard and optional ways for connecting to the communications
line.
Modular Jack Connectors
The standard Data Shelf back panel has 16 8-pin modular jacks, one for
each modem. These jacks provide the interface for connecting
individual modems to the telephone line. Each 8-pin jack has contacts
that are used in various combinations depending on the type of
service installed. Leased-line modems, by comparison, have four
contacts: a transmit pair and a receive pair.
For a description of the modular jack functions, refer to Table E-1 in
Appendix E on page 43.
Optional Backplanes for Dial Backup Connections
Two optional Data Shelf backplanes are available for use with dial
backup modems. These backplanes provide either modular or mass
termination jacks for both dial-up and leased line telephone line
connections. Figure 1-4 on page 10 and Figure 1-5 on page 11 show
examples of these backplanes.
Modems with dial backup capability can switch to a dial-up line if the
leased line fails. For this reason both the TELSET/LL and TELCO
connections must be made. If the option is not used, connect the
modem to the appropriate service, either leased line or dial-up. If
standard modems (no dial backup capability) are installed they are
limited to connection to the TELCO only.
For a description of the modular jack functions, refer to Table E-1 in
Appendix E on page 43.
NOTE: Telco jack pin functions are identical for both standard
and dial backup modems. Similarly, DTE connectors are the

Installation
Page 20
same as for standard modems.
Installing and Removing Power Modules
Power modules generate power that is bused to the 16 modem edge
connectors on the recessed power bus. Power modules are available in
AC and DC versions.
AC Power Module
The AC power module is a 2-slot module designed for the RM16M
ACV-R Data Shelf. The RM16M ACV-R Data Shelf can hold a
maximum of one AC power module.
The AC power module consists of:
vTwo transformers (one for slots 1 through 8 and the other for
slots 9 through 16)
vTwo push-button circuit breaker switches on the front panel
vA red 3.5 Amp light on the front panel
vA 115 or 230 VAC connector on the back of the module
Table 2-3 lists the connector pin functions on the AC power module.
