Optic Inter-Repeater Link (FOIRL) segment and a UTP (10BASE-T) segment.
Table 1 lists the product line.
Table 1: The AT-MR118FT and AT-MR128FT Characteristics
Repeaters are used for two principal reasons. They are:
❑To extend a signal beyond its normal length of transmission
❑To complete a network connection in instances when one cannot be made
Segments on either side of both repeaters support full length, fully repeated
transmission. Only the fiber optic segment supports both full- and half-repeated
transmission.Both segments allowthe maximumnumberof nodesspecified by the
IEEE 802.3 specification. The repeaters are both compliant with both IEEE 802.3
and Ethernet standards. Both repeaters use state-of-the-art technologies,
including a custom Application Specific Integrated Circuit (ASIC) and Surface
Mount Technology (SMT), which provide enhanced functionality, increased
reliability and improved performance.
Network diagnostic LEDs are provided on the front of the micro repeaters to aid
in troubleshooting and fault isolation. Both segments have On Line, Collision,
Receive, Transmitand Link indicators.Inaddition,both repeaters haveacentral
Power indicator. Refer to “Indicators” on page 7 for more information.

Overview

Dimensions of Internal and External Micro Repeaters
The primary difference between the AT-MR118FT and the AT-MR128FT
repeaters is that the AT-MR128FT is alarger repeater because both the repeater
and the power supply reside together in one chassis. The dimensions of the two
repeaters are shown below in Table 2.
Table 2: CentreCOM Micro Repeater Dimensions
The AT-MR118FT has a separate external power supply. Consequently, it is
smaller,enablingyoutoconnecttoahuboraMediaAccessUnit(MAU)whenyour
physical environment does not allow space for a larger repeater.
The CentreCOM Micro Repeaters are both relatively small in size and provide the
complete functionality of larger repeaters that contain many ports, including
packet regeneration and network partitioning.
Full- and Half-Repeater Modes
The AT-MR118FT and AT-MR128FT micro repeaters support both full- and
half-repeater modes. You can select the appropriate mode required, using the
full-repeater/half-repeater switch located next to the fiber optic ports.
Full-repeater modeenables a simple retransmission of signals from the fiber optic
port to the UTP port and vice versa, using the Packet Retiming Controller (PRC)
to ensure bit integrity in signal packets. The packet regeneration results in a
higherperformance networkbyregenerating preamble,retiming thedatapackets
and extending collision fragments to ensure collision enforcement by all nodes.
Half-repeater mode aids in reducing the effective repeater count in networks
capable of supporting half repeaters. This reduction is achieved by taking
advantage of the lower distortion in the fiber optic media. The technique is used
whenasignalissentfromthefiberoptic port to theUTPport,therefore,repeating
occurs in only one direction.
The half-repeater mode is used to reduce the number of repeaters a signal must
traverse so that the four repeater rule restriction is not violated. For example, if
you are using four repeaters, and two of them are set for half-repeater mode, the
effective repeater count is three, enabling you to add another repeater without
violating the four-repeater limit. If you want to realize the benefit of a repeater
reduction, you have to remember to initiate half-repeating on two repeaters
connected to each other.

The UTP-to-fiber optic port transmission needs to be regenerated by
the PRC to ensure integrity of timing. Because the UTP-to-fiber optic
transmission is routed through a regenerating chip, it uses the full-
repeater strategy and does not provide the repeater count reduction
benefit associated with the half-repeater strategy.
Connector Types
Each repeater supports both fiber optic and UTP versions (RJ45 connection). The
fiberoptic repeateris availablein eitheran SMAand STversion. TheSMA screws
into a threaded receptacle. The ST twists into a twist-lock receptacle.
Power Requirements
The power requirements of both the AT-MR118FT and the AT-MR128FT are
described below.
External Power Supply Micro Repeaters
The AT-MR118FT has an external universal AC input/DC output power supply.
Locate a 100-240 VAC, 50/60 Hz outlet and plug in the standard-equipment power
cord. The power cord is only supplied in the U.S.A. version.
Use only the AC power adapter. Using another manufacturer’s power
adapter may permanently damage your micro repeater and void your
warranty.
Connect the power connector from the AC power adapter to the micro repeater.
The Power indicator should illuminate.
Internal Power Supply Micro Repeaters
The AT-MR128FT has an internal universal AC input/DC output power supply.
Locate the 100-120/200-240 VAC, 50/60 Hz power outlet and plug in the standard-
equipment power cord. The power cord is only supplied in the U.S.A. version.
Insert the power plug into the micro repeater. The Power indicator should
illuminate.

Cabling
Two types of cabling exist for the AT-MR118FT and AT-MR128FT. They are:
❑UTP (10BASE-T)
❑Fiber Optic (10BASE-FL/FOIRL)
The 10BASE-T cabling type is UTP while 10BASE-FLand FOIRL is fiber optic
with FL covering a greater distance than FOIRL. Both cabling types have IEEE
802.3 specifications and limits associated with them. They are described in the
following sections. If you need detailed information on cabling, see Appendix A.
For more information, read the IEEE 802.3 specification where cabling
regulations are outlined.
10BASE-T (UTP) Connections
The micro repeater’s UTP connections support a full 100 meters (328 ft.) of UTP
cableperthe 10BASE-Tspecification.This twistedpairsegment connectsdirectly
to either a Data Terminal Equipment (DTE) or transceiver. The RJ45 connector
maybepluggeddirectly totheUTPport.ThecableshouldbeatleastLevel3UTP,
100 Ωimpedance, 22 to 26 American Wire Gauge (AWG), a minimum of three
twists per foot, and should not exceed 100 meters (328 ft.) in length.
10BASE-T UTP media was implemented to reduce Ethernet wiring
costs. Much of the existing cabling is not suitable for Ethernet 10 Mb
data rates. Care must be taken to ensure the UTP wiring used for
10BASE-T is able to carry these Ethernet data rates before a
10BASE-T network solution is implemented. Unlike the coaxial
Ethernet,10BASE2and10BASE5architectures, the 10BASE-TUTP
protocol is point-to-point wiring. For more detailed information on
10BASE-T, see Appendix A.

FOIRL or 10BASE-FL Fiber Optic Connections
Hazardouslightemissionsmay exist infiberopticsystems.Severe eye
damage may result if precautions are not taken. Never look into a
transmitting fiber optic device, transceiver, repeater or cable.
The IEEE 802.3 10BASE-FL port supports up to 2,000 meters (6,560 ft.) of
multimode duplex fiber optic cable in a point-to-point link which directly attaches
two devices. Duplex refers to support for fiber optic cable pairs, enabling a two-
cable fiber optic connection with transmit mode dedicated to one cable and receive
mode on the other. 10BASE-FL supports connections of 2,000 meters (6,560 ft.)
while FOIRL supports connections of 1,000 meters (3,280 ft.). FL is compatible
with FOIRL, but restricts distance to 1 km. The wide dynamic range of the fiber
optic interface on the AT-MR118FT and AT-MR128FT allows for an easy
installation. Both the SMA and ST connections are industry-standard interfaces.
Make sure the fiber optic cable connector is not forced into the ST
receptacle. The ST connector is keyed. Gently rotate the connector
plug until the key slips into the notch of the fiber optic receptacle.

Operation
The AT-MR118FT and AT-MR128FT repeaters both retime and regenerate the
Ethernet signal symmetry and regenerate the packet preamble. The micro
repeaters also count the number of consecutive collisions. If this number reaches
32, then the repeater will take the segment Off Line (partition) to prevent a total
network failure. This process is known asautomatic segmentation. If one valid
Ethernet packet is received on that segment, the repeater will place the segment
On Line automatically, thus disconnecting problem segments and reconnecting
valid segments.
Switches
TheAT-MR118FT andAT-MR128FT repeaterseach have twoswitches. Theyare:
❑A full-repeater/half-repeaterswitch
❑A straight-through/cross-over selection switch (MDI/MDI-X)
The full-repeater/half-repeaterselection switch is used to select the half- or full-
repeater functions. Thestraight-through/cross-over selection switch enables and
disables the internal cross-over function. It indicates whether straight-through
(MDI) or cross-over (MDI-X) connections are being enabled.
Indicators
The following diagnostic indicators are common to the micro repeaters. The
AT-MR118FT and AT-MR128FT both have five indicators per port. In addition,
there is a power LED for the entire repeater. Each indicator is described below.
Power—Indicates the AC power adapter or power supply is providing power to
the repeater.
Collision—Indicates a collision detected on that port.
On Line—Indicates when the port is ready for operation and is not partitioned.
Receive—Indicates when a packet is received on that port. Brief flashes indicate
low traffic levels.
Transmit—Indicates when a packet is transmitted.
