TxPORT reserves the right to revise this publication from time to time and make

The controls, indicators and test features are identical for both units except for the front
panel ‘FAR’ indicator, which is found only on the 200 CS U. Each unit uses LED in dicators to convey major alarm conditions and looping status. Loop s are initiated using
the network test switch.
3.1 Testing
The front panel test switch is used for local testing. When placed in the local loop
mode (LOOP), the unit loops the signal from the customer equipment (DTE IN) back
to the customer equipment (DTE OUT). It also loops the received signal from the T1
facility (NET IN) back to the T1 facility (NET OUT). When moved back to ‘NORM’,
the local loopback is removed.
The unit can also be looped remotely by generating towards it a standard CSU line
loopback code (000 01 repeating for Š 5 se conds, framed or unframe d). Once looped,
the received signal from the T1 facility (NET IN) is regenerated and transmitted back
to the T1 facility (NET OUT). The unit can be unlooped remotely by generating
towards it a standard CSU line unloop code (001 repeating for Š 5 seconds, framed or
unframed).

DIP switch S1-6 configures the unit to either generate an unframed all ones (AIS) signal to the DTE or to pass the received data from the network to the DTE. The 200 unit
responds to the facility data link (FDL) loop (PLB, 0000111011111111) and unloop
command messages (0011100011111111) .

1.0 Introduction
The TxPORT Productivity Series 20 0 ESF CSU and 210 CSU provide an eco nomical
solution for providing the T1 interface between customer premise equipment and T1
facilities (telco or private). Each unit is compatible with all T1 carrier transmission
equipment and is designed to comply with all industry standard specifications. Both the
transmitted and received 1.544 Mbps signals are conditioned.
The 200 unit is an industry standard, ESF T1 channel service unit which supports ESF
performance monitoring, testing, and performance reporting per AT&T 54016 and
ANSI T1.403.
The 210 unit is an industry standard, frame transparent T1 channel service unit. It
detects and activates network initiated loopbacks, monitors bipolar violations, and
maintains pulse density of the transmitted signal. The unit works with any T1 line format and is transparent to framed (D4 or ESF) or unframed T1 signals. The 210 unit is
transparent to line coding an d may operate with either AMI or B8ZS.
2.3 Connections
Both 200 and 210 CSU rear panels have RJ48C connections for the net work and DTE
interface and a terminal strip for the power connection. The fol lowing paragraphs describe these connections.
2.3.1 DTE and Network Connections
The equipment and network physical interfaces are standard RJ48C 8-pin modular
jacks with the following pinout.

Both units are constructed for stand- alone (tabletop) use but may be installed in an
equipment rack or cabinet (requiring optional rack m ount hardware). The front and rear
panels of the two units are sim ilar. Any differences will b e noted in the appropriate
places throughout this manual.
Each unit provides ALBO circuitry on the network receive path. The network ALBO
supports a receive range of +1 dB to -30 dB . Th e DTE supp ort s DSX 1 signa l ran ges up
to 655 feet. The units also provide LBO circuitry on both network and DTE. The network transmit LBO is user selectable (from 0 dB to -22.5 dB). The DTE transmit LBO
is user selectable in five incremental ranges from 0 to 655 feet.
Both CSU units operate from an externally provided -24 or -48 VDC power source.
Network and DTE connections are made through RJ48C type connectors. The u nits
have primary and secondary surge prote cti on on b oth th e net work a nd DTE side (m eet ing the UL 1459 requirements ).

Network LBO: Positions S1 -1 and S1-2 set the network line build out signal level of
data transmitted towards the T1 facility. The output level is factory set at 0 dB
be attenuated by -7.5 dB, - 15 dB, or -22.5 dB if operating conditions require a change.
The telco should provide the proper setting to the user. If unsure of the exact setting,
then leave it at 0 dB.
DTE LBO: Positions S1-3, S1-4, and S1-5 set the DTE line build out transmit signal
value towards the customer equipment. The value should match the cable length from
the CSU DTE port to the attached equipment.
Loop Mode: Positi on S1-6 selects the op erating mode du ring an active payload loo pback. The unit can be optioned to ‘generate’ un framed all ones (Alarm Indicati on Signal) to the DTE during a remote loop or to ‘pass’ the received network signal to the
DTE on a remote loop.

AMI /B8ZS: Position S1-7 is used only on the 210 CSU as follows: In the ‘Transparent’ mode, the unit is transparent to line code information. In the ‘Conversion’ mode,
AMI signals from the DTE are converted to B8ZS and B8ZS signals from the network
to the DTE are converted to AMI. This mode provides clear channel capability across

to operate the equipment.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including interference that may
cause undesired operat ion.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection agains t harmful interference when the equipment is operated in a
commercial environment. This equipm ent generates, uses, and can radiate radio frequency energy and if not installed and us ed in accordance with the instructio n manual,

Operating Mode: Position S2 -1 sets the operating mode of the unit. In the 54016
mode, the unit resp onds only to 54016 CS U messages. In the T1.403 mode, the unit
responds to ANSI loop/unloop commands and generates a PRM every second, but will
not respond to 54016 messages. The two modes are exclusive of each other.

2.1 Supplied Materials
The TxPORT 200 and 210 CSUs are shipped from the factory with the 200/210 CSU
reference manual. The user may require ad diti onal ite ms for the in stalla tion and ope ra-
tion of the units. Refer to Section 1.4 for complete ordering information.
2.2 Unit Configuration
The following sections describe the configuration of the 200/ 210 CSU. These units
were designed to be operated from manual DIP switch control. Refer to the diagrams in
this chapter for switch locations. The 210 unit is transparent to framed (D4 or ESF) or
unframed T1 signals. It is also transpa rent to line codin g and may operate with either
AMI or B8ZS.
On power up, each unit is configured to the hardware settings of the option switches.
Subsequent changes to these settings will not take effect until the unit has been reset.
This may be acc omplished e ither by removing and then reapplying power or by pushing the test switch toward ‘LOOP’ and then quickly back to ‘NORM’. The unit will
then recycle through its LEDs and read the new configuration.
