designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Operator's Manual
v

FCC PART 68 REQUIREMENTS
This equipment complies with Part 68 of the FCC rules. On the bottom of this
equipment is a label that contains, among other information, the FCC
registration number and ringer equivalence number (REN) for this equipment.
Upon request of the telephone company, you should provide the FCC
registration number and the ringer equivalence number (REN) of the equipment
which is connected to your line. The D-SERV DSU/CSUs registration number is
F8IUSA-74432-DE-N and the REN is 0.0B.
The D-SERV DSU/CSU operates with a 1.544 Mbit/s/s digital channel using an
RJ48C USOC 8-pin modular connector on the back of the D-SERV unit.
The REN is used to determine the quantity of devices which may be connected
to the telephone line. Excessive REN’s on the telephone line may result in the
devices not ringing in response to an incoming call. In most, but not all areas,
the sum of the REN’s should not exceed five (5.0). To be certain of the number
of devices that may be connected to the line, as determined by the total REN’s
contact the telephone company to determine the maximum REN for the calling
area.
The service code is 6.0N. The Facility Interface Code is 04DU9-C for lines using
the Extended Super Frame format, 04DU9-B for lines using the Super Frame
format, and 04DU9-S for lines using the B8ZS format. All D-SERV models
connect to the network using an RJ48C connector.
The telephone company must be notified before removal of a D-SERV DSU/CSU
connected 1.544 Mbit/s/s digital service. If the telephone company notes a
problem they may temporarily discontinue service, and will notify you of this
disconnection. (If advance notice is not feasible, you will be notified as soon as
possible.) When you are notified you will be given the opportunity to correct the
problem and informed of your right to file a complaint with the FCC.
The telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect the operation of the equipment. If this
happens, the telephone company will provide advance notice in order for you to
make the necessary modifications in order to maintain uninterrupted service.

1INTRODUCTION
General Description
The Kentrox D-SERV DSU/CSU is a low cost, intelligent, single port
T1 DSU/CSU that provides channelized connections to T1 or
Fractional T1 (FT1) services. The serial data signal can operate in
increments of 56 Kbit/s or 64 Kbit/s, up to the full band width of
1.536 Mbit/s. The network T1 signal is always 1.544 Mbit/s. The CSU
portion of the D-SERV DSU/CSU insures that the signal is compatible
in format and pulse density with T1 requirements. The D-SERV
DSU/CSU provides line protection from voltage spikes, surges and
line crossings coming from the public network. In addition, the
D-SERV DSU/CSU generates alarm signals and performs loop backs
to aid in the turn up and trouble-shooting of expensive T1 circuits.

Switch S2 — Data Port LOS Processing
Some DTE equipment changes the state of the RTS and/or DTR signal
lines on a regular basis which the D-SERV DSU/CSU may interpret as
an LOS condition. Options for determining a data port LOS condition
are if the RTS signal line is de-asserted, the DTR signal line is
de-asserted, or if both of the signal lines are de-asserted at the same
time. The D-SERV DSU/CSU also provides the option of not
monitoring for data port LOS by ignoring the condition of the RTS
and DTR signal lines.
Switches S2-7 and S2-8 configure this option.
NOTE: If a data port LOS condition occurs, all active channels
will transmit All Ones out to the network. All idle
channels will continue to transmit Idle code. If the unit
has been configured for data port timing (tail circuit
timing) the timing source will switch to internal clock
timing.

Switch S4 — Starting DS0 Channel Selection
If fewer than 24 channels have been activated, the user can select
which channel is first. For example, if four channels have been
activated any of the eight channel starting options may be selected.
Unused channels remain idle.
Switches S4-1, S4-2, and S4-3 select the starting channel.
NOTE: It is not allowed to activate more channels than can be
accommodated between the starting channel and the
24th channel. For example, if ten channels have been
activated and channel 16 has been chosen as the
starting channel the D-SERV DSU/CSU will alert the
user of a configuration conflict.
In the event of a conflict the D-SERV DSU/CSU will
flash the front panel POWER, RED ALARM, and DATA
LEDs red. The last valid starting channel selected by
the user is used until the configuration error is
corrected by the operator.
