1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model IM2RC/F-128K compo-

nents to be free from defects, and will—at our option—repair or replace
the product should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials,
and does not cover customer damage, abuse or unauthorized modifi­cation. If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above. Under no
condition shall Patton Electronics be liable for any damages incurred
by the use of this product. These damages include, but are not limited
to, the following: lost profits, lost savings and incidental or consequen­tial damages arising from the use of or inability to use this product.
Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model IM2RC/F-128K generates and uses radio frequency
energy, and if not installed and used proper ly—that is, in strict accor­dance with the manufacturer's instructions—may cause interference to
radio and television reception. The Model IM2RC/F-128K has been
tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart J of Part 15 of
FCC rules, which are designed to provide reasonable protection from
such interference in a commercial installation. However, there is no
guarantee that interference will not occur in a particular installation. If
the Model IM2RC/F-128K does cause interference to radio or television
reception, which can be determined by disconnecting the unit, the user
is encouraged to try to correct the interference by one or more of the
following measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna and/or plugging the receiv­ing equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).In the event the
user detects intermittent or continuous product malfunction due to
nearby high power transmitting radio frequency equipment, the user is
strongly advised to use only data cables with an external outer shield
bonded to a metal or metalized connector at both ends. Shielded
cables must be used on the network connection to satisfy compliance
with the Electromagnetic Compatibility (EMC) directive.

2.2 DESCRIPTION

The Patton Model IM2RC/F-128K is a rack-mountable rear card

that allows Patton baseboard modems to connect to modified 128 kbps
G.703 devices. With the IM2RC/F-128K you can achieve high speed
G.703 network extension, dedicated high speed internet access,
remote LAN access,...the possibilities are endless! Supporting 128kbps
clear channel, the IM2RC/F-128K can set its own clock or it take clock­ing from the G.703 network.

The Model IM2RC/F-128K meets baseband modem function cards
such as 1094ARC and 1095RC in the mid-plane of Patton’s 2U (3.5”)
rack chassis. G.703 access is accomplished via a 120 Ohm RJ-45
jack. The twisted pair line connections between the baseboard
modems (2-W or 4-W) are made with the second RJ-45 jack.

The Model IM2RC/F-128K features on-board transformer isolation
and surge protection as well as compliance with ITU-T G.823 Jitter
Control Specifications.

NOTE: Packages received without an RMA number will not be

accepted.

WARNING! This device is not intended to be connected

to the public telephone line.

3.0 CONFIGURATION

This section describes how to configure the IM2RC/F-128K rear
card. Please refer to the appropriate function card user manual to con­figure the function card.

3.1 CONFIGURING THE IM2RC/F-128K HARDWARE SWITCHES

The Model IM2RC/F-128K rear card features an eight position DIP
switch mounted on the rear of the printed circuit board. Use these
switches to configure G.703 operational and timing modes. Figure 1,
below shows the position of the DIP switches on the board.

Figure 2 shows the orientation of the DIP switches with respect to
the “ON” and “OFF” positions.

Switch S1:

Reserved for Future Use

Switch S1 is reserved for future use and should remain in the Off

position.

Switch S2: Operation Mode

Use Switch S2 to set the IM2RC/F-128K for Clear

Channel/Unstructured mode.

S2

Setting
Off Clear Channel/Unstructured Mode (default)
On Reserved for Future Use

Switches S3 Timing Mode

The setting of Switch S3 determines the source of the system tim-

ing.The system timing may be provided by:

1. The G.703 network, or

2. The local function card or remote baseband

modem/CSU/DSU (either a rackable function card or stand­alone unit).

WARNING! The IM2RC/F-128K card contains sensitive inte-

grated circuitry. Failure to ground yourself during configuration
may result in damage to the IM2RC/F-128K card or the front func­tion card.

Notice! The RJ-45 G.703 port of the Model IM2RC/F-128K is

intended to connect to telecommunication network voltage
(TNV) circuits which may carry dangerous voltages. Therefore
the power and network cables must be disconnected prior to
switch configuration.
