2. Product Overview
The BLACK BOXCityLANFDDI Extended Distance Repeater
(LCL163A/LCL164A) supports 100Mbps ANSI X3T9.5/X3T12 data over greatly
extended distances on single-mode fiber.
2.1 Drive Distance
On the multimode side the LCL163A/LCL164A repeaters support a distance of
2km. The single-mode interface supports a 40km drive distance as standard.
With high power SC optics on the single-mode interface, a distance of 60km is
obtainable.
2.2 Station Count
Any number of repeaters can be used within a network. The only constraint
being that each device is included in the total station count for the overall ring.
Each repeater has 4 physical layer entities. There is a re-timing function on each
port, therefore each repeater is considered as 2 stations. The default value for
the number of physical layer entities on a ring is 1,000, i.e. 500 Dual Attach
Stations (DAS).
2.3 Power Supply
The unit is powered using a nominal 100V-240V-AC supply (+/- 10%). The
power supply is universal across all acceptable input voltage ranges.
A 48V-DC power supply is available as an order time option.
2.4 Ergonomics
The dual repeater is housed in a standard 19”, 1U high rackmount case (165mm
deep) for optimum use of rack space.
Variants of the CityLANFDDI repeaters are available as single and dual
repeaters. Dual repeaters (LCL164A) support the connection of a DAS via two
fiber pairs. The single repeater (LCL163A) supports an SAS connection. The
units are all functionally the same and two single repeaters are functionally the
same as a single dual repeater.

2.5 Contact Alarms
The unit has dry contact alarms to report failure conditions. These operate as
normally open and normally closed contacts. See Section 6.5, Alarm Reporting,
for details.
2.6 Management Interface
A serial management interface provides out-of-band control and management
of the LCL163A/LCL164A, either via modem or via a direct VT100 terminal
attachment. See Chapter 6, Management Serial Interface.

Figure 2: Linking Three Buildings around a City using LCL163A/LCL164A
Extended Distance Repeaters
In the above application, several local sites are interconnected using
LCL163A/LCL164As. Two of the A and B ports of the multimode local rings are
connected to the multimode A and B ports of the LCL163A/LCL164A. This
extends the ring via the single-mode fiber to each of the other sites, where they
are returned to multimode A and B interfaces for connection to that backbone.

In this application, the single attach ports of the routers are inter-connected
using two LCL163A repeaters. The router port is simply connected to either
multimode port (i.e. A or B). The corresponding single-mode fiber is taken to
either port of the far end LCL163A which in turn is connected to the router via
the corresponding multimode ports. For dual homing connections, dual
LCL164A repeaters may be used by simply connecting each port of the router to
the A and B ports via the single-mode fibers to the far end A and B ports and
subsequently to the multimode M-ports of a concentrator.

4. Installation
4.1 Operating Modes
For the LCL163A/LCL164A to operate correctly in a ring the Test Switch fitted
on the back panel must be set to the Normal position. The LCL163A/LCL164A
needs no further configuration to operate simply in a ring. However, for
maximum efficiency of alarm reporting over extended distances, four
management operating modes are available.
1) Direct Terminal Connection.
2) Remote Terminal Connection (dial in).
3) Remote Terminal Connection (dial out).
4) Remote Controller Device using simple asynchronous commands to
gather information from the LCL163A/LCL164A.
In all operating modes, dry contact alarms can be configured to indicate error
conditions.
4.1.1 Mode 1 - Direct Terminal Connection
This is the factory default configuration.
The RS232 cable supplied with the LCL163A/LCL164A allows connection of a 9
way serial port of a PC or laptop to the LCL163A/LCL164A. The PC should
have a VT100 style terminal emulator loaded which requires the following
configuration:
9600 baud
8 bits
1 stop bit
No parity
XON/XOFF flow control.
After power on, the terminal displays the self-test sequence followed by the main
screen showing status information for the LCL163A/LCL164A.
To connect an unattended Auto Answer Modem to the LCL163A/LCL164A in
terminal mode, please NOTE: At start up LCL163A/LCL164A sends the
initialization string “ATQ1&D2&S1&C1”.

LONG DISTANCE FDDI REPEATER
17
This sets the modem to Quiet Mode, uses DTR, DSR and DCD. If you require
that the modem be capable of being dialed into after a power down of the
modem, it is vital that you configure the modem to 9600 Baud, Auto Answer held
permanently in its own memory. Check your modem user manual for details of
setting the modem into unattended auto answer mode.
When configured to “Terminal” the LCL163A/LCL164A makes no use of DCD or
DSR. DTR is always asserted.
To return to this mode from any mode, connect the terminal and press “CTRL_
Z”, followed by “CTRL_L”.
4.1.2 Mode 2 - Remote Terminal Connection (dial in)
Dial in access to the LCL163A/LCL164A is made using modems and a remote
VT100 or PC emulating a VT100 terminal. Figure 5 shows a typical link.
To connect the modem to the LCL163A/LCL164A, use a standard 25 way
straight through serial cable.
Configure the modem to 9600 Baud, Auto Answer, Enabled DTR. Other control
lines are not required. NOTE: The LCL163A/LCL164A sends an initializer string
to the modem on power up, as described in Mode 1.
At the remote site the VT100/PC emulator is connected to the remote modem.
See the VT100/PC manual for the cable required to connect to that modem.
For dial in access it is suggested that you use a Hayes compatible modem. The
“Connected To” management field should be set to “modem” which will send the
initializer string to the modem each time a critical event is to be reported as well
as on power up. See Section 6.3.11 for details of the “Connected To” field.
Dial in access is commonly used with the dry contact alarms that indicate a
condition to a control center which subsequently dials into the unit to ascertain
the nature of the alarm. See “Alarm Reporting” in Section 6.5 for details of
contact devices.
4.1.3 Mode 3 - Remote Terminal Connection (dial out)
For those systems where direct dial out access is required, the unit may be
configured to dial a remote location via a Hayes compatible modem whenever a
fault condition occurs.

LONG DISTANCE FDDI REPEATER
18
Configure the modem to 9600 Baud, Monitor DTR.
The LCL163A/LCL164A will automatically request use of Data Set Ready and
Carrier Detect of the Hayes modem, whenever a critical event is to be reported,
by using the “&D2&S1&C1” control string.
Using a directly attached terminal (see Mode 1 above) and referring to Section
6.3, configure the LCL163A/LCL164A “Connected To” field to “Modem” and
include the telephone number of the remote site in the “Modem Init String”, in
the form “D <number to dial>” e.g.: Modem Init String ATD 123 456 789.
Set the events that you require the modem to dial out on. See “Alarm
Reporting” in Section 6.5. Save the changes as you leave edit mode.
NOTE: Once saved these choices, including phone numbers etc., are held in
non-volatile memory within the LCL163A/LCL164A. Consequently problems
with borrowed or swapped modems are avoided.
Attach the modem using a 25 way straight through cable.
The LCL163A/LCL164A will dial out whenever one of the “Alarm” conditions
occurs. If the far end is busy or unavailable, the LCL163A/LCL164A will retry at
minute intervals until the call is answered.
4.1.4 Mode 4 - Remote Controller Device
To permit a remote device to interrogate the LCL163A/LCL164A, a simple
control interface is included that permits a remote station to be programmed to
poll the LCL163A/LCL164A for specific information on a Command/Response
basis sent line by line.
To use the command mode, attach a terminal as described in Mode 1 above and
edit the Display Mode to be line by line.
In this mode, the LCL163A/LCL164A can be directly attached to the device or a
terminal or connected to via a modem for dial in or out access as described in
Modes 1, 2 and 3.

4.2 Step by Step Installation
1. Decide on the operating mode that best suits the system (see Operating
Modes).
2. Attach a PC running a VT100 emulator using the cable supplied. Set the
VT100 to 9600 baud, 8 bits, 1 stop bit, no parity, XON/ XOFF flow control.
3. Using the terminal emulator, edit the LCL163A/LCL164A configuration to
support:
a) Chosen operating mode.
b) Alarm conditions.
See Section 6, Management Serial Interface for details of how to edit the
LCL163A/LCL164A fields.
4. Check the loss budgets for the single-mode and multimode interfaces. Use
the table below to check the required maximum and minimum losses for
each link versus connector/product type.
Connector Type Receiver
Saturation
Minimum Loss between
LCL163A/LCL164 as (to
avoid saturation)
Maximum Loss
(Link Budget)
Multimode MIC -14dBm 012dB
Multimode SC -14dBm 012.5dB
Single-mode FC
(Standard Power) -14dBm 7db 19dB
Single-mode SC
(Standard Power) -8dBm 0dB to like device or 8dB
to High Power remote
device
19dB
Single-mode SC
(High Power) -3dBm 3dB 30dB
If the link loss is less than the minimum required or if the received power
from the remote equipment is greater than the receiver saturation figures,
then optical attenuators must be used.
