Chapter 1 Overview
The Digium Redundancy Series of products, R-Series, are versatile
devices used to facilitate physical layer switching of PSTN interfaces for
Asterisk based redundant PBX configurations. R-Series is among several
key technologies Digium is intr oducing to empower Asterisk integrators
to create advanced high-reliability failover solutions.
The basic application sequence shown below depicts the following:
1. While in a normal state, the R-Series unit r outes the input lines from
the PSTN to Server A (Primary).
2. After a failure of Server A, the R-Series unit routes the input lines
from the PSTN to Server B (Secondary).
3. After Server A re covers, the R-Serie s unit c ontin ues to route the in put
lines from the PSTN to Server B.
4. After a failure of Server B, the R-Series unit routes the input lines
from the PSTN to Server A.

Digium, Inc. Page 23
Chapter 2: Unit Installation
USB Requirements
The servers which connect to an R-Series unit using the USB Console,
Primary USB, and Secondary USB ports must support USB 1. 1 or greater
for compatibility. If either server does not support at least USB 1.1, an RSeri e s unit w ill not work .
Digium, Inc. Page 24
Chapter 2: Unit Installation
Hardware Installat ion
This section describes how to properly install the hardware for an RSeries unit.
Grounding
The R-Series unit must be properly grounded for safety reasons. If the
unit is not properly grounded, damage could arise to the R-Series unit
and/or other equipment connec ted to the R-Series unit. If an R-Series unit
is damaged while it is improperly grounded, the warranty on the R-Ser ies
unit is void.
A ground lug is located on the opposite side from the front panel of an RSeries unit. Attach an appropria te length and guage of wire to the ground
ring terminal. The wire length should be as short as possible, and guage
should be 18 AWG or greater . Stranded or solid wire is acceptable. Wire
is not provided with the R-S eries unit . Slide the ground ring term inal ove r
the ground lug. Then fasten the ground rin g terminal to the ground lug
using the groun d nut. The ground nut must be turned clockwise to tighten
it onto the ground lug. The opposite end of the wire that is connected to
the ground ring terminal should be secur ily fastened to an unpainted
metalic section of a properly grounded server rack. A connector for the
opposite end of the wire is not provided with the R-Series unit.
Note: Taking into consideration the requir ements of a ll equipment that
is connected to or sharing the rack, the server rack should be properly
grounded. Refer to the manufacturer of the rack for instructions on
how to properly ground the rack.
Digium, Inc. Page 25
Chapter 2: Unit Installation
Mounting
Place one of the rac k mounting ears on the right side of the R-Series unit.
Line up the hol es from the rack m ountings e ar to the t hreaded hole s o n the
side of the R-Series unit. Two screws should be inserted and turned
clockwise to fasten the rack mounting ear. Repeat these steps when
installing a rack mounting ear on the left side of the R-Series unit.
A typical equipment rack installation would have an R-Series unit
mounted on the opposite side of the rack as the servers. Use 2 screws on
each rack mounting ear to secure the R-Series unit to a rack.
Setting Dev ice I D Dial
The Device ID dial should be set to a number which is unique across all
R-Series units that co-exist in an installation. The Device ID assignment
for your first device should be 0, second device should be 1, third device
should be 2, and so on.
Connecting Ports (Powering the Unit)
A description of each of the front panel connectors on an R-Series unit is
available in the section titled Front Panel Identification on page 20.
Please refer to that section to determine what should be connected to each
connector.
Connections to an R-Series unit should be made in the following order.
1. Primary
2. Secondary
Digium, Inc. Page 26
Chapter 2: Unit Installation
3. Passthr ough Input (optional) - Reserved for future use.
4. Input or Alternate Input (n ot both)
5. Primary USB
6. Secondary USB
7. USB Console
An R-Series unit will receive powe r from any of the thre e USB
connections (USB Console, Primary USB, Secondary USB). No othe r
power source is required.
Note: You may have t o apply a decent amount of force to disconnect a
USB cable from an R-Series unit. This is normal. The USB connectors
used in the R-Series units are high-retenti on to help prevent accidental
disconnection.
General Recommendations
Using an R-Series unit in conjunction with a USB hub may have
undesirable resul ts.
Each server connected to an R-Series unit should be powered from a
different powe r source.
It is highly recommended that each server co nnected to an R-Series unit
be equipped with sufficient surge protection to reduce the risk of damage
to the server and R-Series unit.
It is recommended that e ach server whic h is connec ted to an R-Seri es unit
be equipped with an uninterruptible power supply that has sufficient
reserve capacity to power the server until electricity is restor ed. A
generator may also be use d as an alternate means of powering the se rvers
while mains power is out.

Chapter 2: Unit Installation
Softw a r e In s t al la t io n
While the R-Series units do not requi re DAHDI drivers in order to
function, DAHDI drivers and other libraries may need to be installed in
order for other Digium hardware products to function when connected to
an R-Series u nit.
Digium hardware which relies on DAHDI requires drivers and libraries
that are not integrate d with the Linux kernel. Digium hardware is only
supported under Linux. Digium recommends CentOS, Debian, Red Hat,
and Ubuntu distrib utions of Li nux. However, many other dis tributi ons a re
supported by Digium Technical Suppor t.
