1.2 FCC Requirements
WARNING: Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the user’s authority
to operate the equipment.
This device complies with Part 15 of the FCC rules. Operation is subject to the follow-
ing two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including interference that may
cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class A digi-
tal device, pursuant to Part 15 of FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio fre-
quency 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. The user will be required to
correct the interference at his own expense.

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. It may
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: Position S1-6 selects the operating mode during an active payload loop-
back. The unit can be optioned to ‘generate’ unframed all ones (Alarm Indication Sig-
nal) to the DTE during a remote loop or to ‘pass’ the received network signal to the
DTE on a remote loop.
A - Generate AIS B - Pass network data
AMI/B8ZS: Position S1- 7 is used only on the 210 CSU as follows: In the ‘Transpar-
ent’ 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
the network without violating ones density requirements.
A - Transparent B - Conversion
Density: Position S1-8 enables ones density insertion per AT&T 62411. The
‘Enabled’ mode allows insertion after 15 successive zeros from the DTE. The ‘Dis-
abled’ mode ignores density control and allows up to 175 zeros to pass towards the net-
work before a loss of signal is declared.
A - Enabled B - Disabled
2.2.2 Configuration Switch S2
Switch S2 is located only on the 200 CSU. This switch provides the following configu-
ration parameters:
Operating Mode: Position S2-1 sets the operating mode of the unit. In the 54016
mode, the unit responds only to 54016 CSU 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.
A - 54016 B - T1.403
Network Line Coding: Position S2-2 sets the network line coding, including conver-
sion.
A - AMI B - B8ZS
