CHAPTER 2: Introduction
2. Introduction
2.1 Features of the Rate Adapter/64
• Connects EIA 232/V.24 DTEs to the
B-channel (64 kbps) of an ISDN connection
• Can be used as a rate adapter in non-ISDN
applications
• Converts EIA-232 data rates of 1200–19,200 bps
• Handles asynchronous or synchronous data
• Compatible with CCITT I.463 or I.460 (V.110)
recommendations
• Compatible with CCITT V.35 or X.21
2.2 Description
The Rate Adapter/64 lets your EIA 232-compliant
DTEs running at up to 19.2 kbps exchange data
over 64-kbps channels on an ISDN circuit.
The Rate Adapter/64 converts the DTE speed (up to
19.2 kbps) of your PCs, terminals, etc., to the Bearer
(B) channel 64-kbps rate associated with high-speed
digital transmission service (ISDN, unformatted
DDS). Thus you can use the same data equipment
you were using with analog data service when you tap
into a high-speed digital line.

With the Rate Adapter/64, you can exchange
asynchronous or synchronous data in full-duplex
operation. The control signals RTS, DTR, CD, DSR,
and CTS are passed through end-to-end, in
compliance with CCITT I.463 (V.110) and I.460
recommendations. Two LEDs indicate when the unit
is powered on and when there is a loss of signal
synchronization.
The Rate Adapter/64 is not limited to the ISDN
environment. It can be used in any application that
requires conversion from EIA 232/V.24 low-speed
data rates (up to 19.2 kbps) to a V.35 or X.21
high-speed (64-kbps) channel.
The lightweight and compact Rate Adapter/64
is easy to install; average installation time is about
10 minutes. Power is supplied by an external
wall-mount power supply for 120 VAC. A 230-VAC,
50-Hz power supply is also available (our part
number PS321E).

CHAPTER 3: Installation
3. Installation
1. Open the unit. With your thumbs, press the
marked areas on the sides of the unit. The top and
bottom covers should separate. You can use a small
screwdriver to pry open the box; Insert the screw-
driver into the slot at an angle. Gently lift the handle
so that the tip of the tool levers downward. Repeat
this procedure for all the marked areas.
Warning
Do not insert the screwdriver straight into the middle of
the slot; this may break off the prongs that secure the
covers.
2. Set Switch 1 (SW1) to the proper EIA-232 data
rate for your DTE, according to the table below.
SW1 SWITCH POSITIONS RATE
12 3
OFF OFF OFF 600
ON OFF OFF 1200
OFF ON OFF 2400
ON ON OFF 4800
OFF OFF ON 7200
ON OFF ON 9600
OFF ON ON 14,400
ON ON ON 19,200
NOTE: SW1 Switch Position 4 is not connected.

3. Set Switch 2 (SW2) to establish synchronous
or asynchronous operation. Use Switch Position 1
of SW2 to choose either sync or async operation:
• Switch Position 1 OFF = SYNC
• Switch Position 1 ON = ASYNC
4. If you select the asynchronous mode, you will need
to set the Rate Adapter/64 to accommodate the
proper character length (including start and stop
bits). Use Switch Positions 2 and 3 of SW2 to set
async data character length.
SW2 SWITCH POSITIONS TOTAL BITS
23
OFF ON 8 bits
ON ON 9 bits
OFF OFF 10 bits
ON OFF 11 bits
NOTE: SW2 switch position 4 is not connected.
5. Close the unit by pressing both halves together.
6. Plug the connector into the AC power supply.
7. Plug the AC power supply into a power outlet.
