The MDR-8000/i/s/u supports the three basic configurations:
• Non-standby – available in all frequency bands – stand alone transmit-
ter/receiver combination
•Hot-standby – available in all frequency bands except 5 GHz (unlicensed)
– pair of transmitters and receivers, both pairs operating on the same set
of go and return frequencies.
•Frequency diversity – available in all frequency bands except 2 GHz and
5 GHz (unlicensed) – pair of transmitters and receivers, each pair operat-
ing on a different set of go and return frequencies.

1.6.2
Ring
Non-standby radios are typically used in ring systems where the radios are
protected by the ring architecture.
1.6.3
Space Diversity Add-On
Space diversity can be added to any of the three basic configurations and
ring systems.
1.6.4
Optical 2 X 4 Configuration
Hot-standby and frequency diversity configuration are available with 2-fiber
or 4-fiber optical interfaces.
1.7
FEATURES AND OPTIONS
Features and options for the MDR-8000/i/s/u series of microwave digital radios are
described in the following paragraphs.
1.7.1
Primary Power
The MDR-8000/i/s/u series radios operate from 20.5 to 60 V dc primary
power with positive or negative ground.
1.7.2
Transmit Power Level Options
The standard radio is provided without a power amplifier (PA) module for
low-power applications. The optional PA module is available for high-power
requirements. There are different levels for the different frequency bands.
Refer to the electrical characteristics table in this section for specific levels.
1.7.3
Differential Absolute Delay Equalization (DADE)
DADEing adjusts the differential absolute delay between the main and
diversity signals in a space diversity configuration. DADEing is an auto-
matic function within the DS1/E1 and OC3 MDR-8000/i/s/u receivers, reduc-
ing the time required for initial turn-up and test.
1.7.4
Trellis Encoding and Time Domain Equalization (TDE)
Trellis encoding (DS1/E1/OC3) ensures that even with the most severe
multipath, only the correct digital data is demodulated. TDE further reduces
the disruptive effects of multipath distortion.
1.7.5
MCS-11 Alarm/Control Interface
MCS-11 is standard in the MDR-8000. The MDR-8000 can interface with
any alarm system that is based on the MCS-11 protocol. Use with the
TSM-2500 network management system to develop a central access point to
monitor and control the transmission system
MDR-8000 Series Radios 3DH03220
General Issue 6, July 2002
1-8
1.7.6
Foreign Alarm Interface
This provisioning option provides serial alarm/status reporting for the
Telemetry Byte Oriented Serial (TBOS) protocol. A wire-wrap adapter is pro-
vided to mate to connector J305 on the backplane.
1.7.7
Relay Interface Option
The optional AE-27AF Relay Interface unit provides relay closure indica-
tions of radio alarms and status. The relay interface also provides up to 16
station alarm inputs and six relay closure control outputs.
1.7.8
Extended Link Monitor Channel
ELMC is standard and performance monitoring, alarm and status informa-
tion, and remote controls are accessible through the ELMC channel, inde-
pendent of network management interfaces.
Optional remote provisioning and downloading capability is provided via an
ELMC option key that is mounted on the controller module.
1.7.9
Automatic Transmitter Power Control Provisioning Option
Automatic Transmitter Power Control (ATPC) is a standard feature that can
be enabled or disabled using the USI provisioning screens. When ATPC is
disabled, transmitter power is fixed at the recommended maximum level.
When ATPC is enabled, transmitter power may be reduced up to 10 dB from
the maximum power level when the far end RSL is above a minimum level.
When ATPC is enabled with timeout, transmitter ATPC activity is limited to
a maximum time without returning to minimum transmit power. After five
minutes of activity, the transmit power is forced to minimum until the far
end RSL returns to normal levels.
1.7.10
Service Channels Provisioning Options
The MDR-8000 provides a 256 kb/s auxiliary channel for servicing the radio.
This is an overhead channel and is independent of the traffic channels. The
256 kb/s service channel contains four 64 kb/s service channels. Three of the
four 64 kb/s channels (Service Channel 1, 2, and 3) can be provisioned on the
USI for a specific use. Service channel 4 is dedicated to radio commands and
ELMC. Service channel 4 is not provisionable. Only 16 kb/s out of the 64 kb/
s in this channel are used.
Service channels at both ends of a hop (and end-to-end in a link)
must be provisioned the same.

Service channel provisioning is interactive. When an option is selected for
any service channel, that option is excluded from selections on the other
applicable service channels. Provisioning options for Service Channels 1, 2,
and 3 are listed:
• Service Channel 1 (64 kb/s channel) – can be used to carry 4-wire audio, RS232
data, or MCS-11 fault alarm information.
•AUDIO 1 and 2 – Two audio provisioning options (AUDIO 1 and
AUDIO 2) are provided for Service Channel 1. Each audio channel is
a 4-wire audio channel that provides off-hook detection, level control, and
E and M-lead signaling. AUDIO 1 also has DTMF decoding that allows a
specific station to be dialed. External connection to AUDIO 1 is J316.
External connection to AUDIO 2 is J317.
• RS232 1 – RS232 Channel 1 is an RS232 formatted data channel that

1.7.12
Capacity upgrade
The number of maximum DS1/E1 lines can be changed to any number
between 1 and 16 to meet expanding system needs. DS3 lines can be
expanded from 1 to 3. The number of available DS1/E1/DS3 lines is deter-
mined by printed circuit boards (capacity keys). Identical capacity keys plug
onto the transmitter and receiver modules. Changing the number of DS1/E1/
DS3 lines requires changing capacity keys. DS1 to DS1 and/or DS3 to DS3
capacity upgrades can be performed in-service on protected systems without
traffic interruption. In non-protected radios, traffic will be interrupted for
the duration of the procedure.
1.7.13
Bandwidth upgrade
Assuming no frequency or band change, DS1 to DS3 conversion can be
accomplished by changing out the I/O interface modules, LBO board, and
capacity keys and installing DS3 software. Electrical DS3 to optical OC3
conversion can be accomplished by changing out the I/O interface modules,
exchanging the LBO board with the auxiliary board, and changing capacity
keys and installing OC3 software. Changing out the LBO or AUX board
requires interrupting traffic for the duration of the procedure.
1.8
USER SYSTEM INTERFACE (USI)
A personal computer (PC) is required to access provisioning, status and alarm infor-
mation, and maintenance control functions (on-line maintenance and troubleshoot-
ing) within the radio. The PC is not supplied with the radio and must be provided by
the user. These functions are performed via the Alcatel USI maintenance program
software (Table 1-2). The PC must be IBM compatible. PC guidelines are addressed
in Table 1-3.
The USI runs on Windows 95

1.8.1
System Security
Password options ensure that only authorized users have access to USI pro-
visioning screens. The level of security provided by the system depends on
how thoroughly the security system scheme is implemented and maintained
by the system administrator.
