1.3 RADIO AND TV INTERFERENCE
The NetLink-T1™ Model 2710 Series generates and uses radio frequency energy, and if not installed and used properly—that is, in strict
accordance with the manufacturer's instructions—may cause interference to radio and television reception. The Model 2710 Series has been
tested and found to comply with the limits for a Class A computing device
in accordance with the speciÞcations in Subpart J of Part 15 of FCC
rules, which are designed to provide reasonable protection from such
interference in a commercial installation. However, there is no guarantee
that interference will not occur in a particular installation. If the Model
2710 Series does cause interference to radio or television reception,
which can be determined by disconnecting the cables, the user is
encouraged to try to correct the interference by one or more of the following measures: moving the computing equipment away from the receiver,
re-orienting the receiving antenna, and/or plugging the receiving equipment into a different AC outlet (such that the computing equipment and
receiver are on different branches).

1.5 INDUSTRY CANADA NOTICE :
The Canadian Department of Communications label identiÞes certiÞed
equipment. This certiÞcation means that the equipment meets certain
telecommunications network protective, operational and safety requirements. The Department does not guarantee the equipment will operate
to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method
of connection. In some cases, the company’s inside wiring associated
with a single line individual service may be extended by means of a certi-
6
Þed connector assembly (telephone extension cord). The customer
should be aware that compliance with the above condition may not prevent degradation of service in some situations.
Repairs to some certiÞed equipment should be made by an authorized
maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions,
may give the telecommunications company cause to request the user to
disconnect the equipment.
Users should ensure for their own protection that the ground connections
of the power utility, telephone lines and internal metallic water pipe system, are connected together. This protection may be particularly important in rural areas.
Users should not attempt to make such connections themselves, but should contact the appropriate electric inspec-
CAUTION
tion authority, or electrician, as appropriate.

2.2 DESCRIPTION
The NetLink-T1™ Model 2710 Series are single port T1/FT1 CSU/DSUs
that provide high-speed WAN connectivity in an ultra-compact housing.
Plugging directly into the V.35 WAN port of a switch, router or multiplexer,
the NetLink-T1™ provides T1 or FT1 access at connection at data rates
of 1.544 Mbps, nx64, and nx56 (n=1 to 24 channels). The Netlink-T1™
is an excellent choice when terminating leased line services, Frame
Relay backbones, internet access as well as LAN-to-LAN services.
The Netlink-T1™ provides digital access to a local WAN service provider
or directly between two facilities over a dedicated 4-Wire circuit. LAN
bandwidth, framing and coding options are programmed via internally
accessible DIP switches or via a rear-mounted EIA-232 control port. The
Netlink-T1™ supports D4/ESF framing options and AMI/B8ZS/B7ZS line
coding. Netlink-T1™ also supports a full range of system and diagnostic
features that make system setup easy.
8
The NetLink-T1™ provides T1 terminations over a modular RJ-48C jack
and comply with jitter tolerance capabilities as speciÞed in ANSI T1.403
and AT&T TR62411. External power options include 120VAC and Universal Interface 100-240VAC.
2.3 SUPPORTED APPLICATIONS
The NetLink-T1™ CSU/DSU provides a T1 (DS1) network termination
between the service provider and customer premises equipment (CPE)
such as a router. The Netlink-T1™ can also be used as a high-speed
short haul modem for campus applications.
The 2710 as the Interface between the Telco and CPE

3.0 CONFIGURATION
The Model 2710 features conÞguration capability via hardware switches
or a software control port. This section describes all possible hardware
and software switch conÞgurations of the NetLink-T1™.
3.1 DIP SWITCH CONFIGURATION
The Model 2710 has eight internal DIP switches that allow conÞguration
for a wide range of applications. The eight switches are accessed by
opening the plastic case with a small screwdriver. Figure 1 (below)
shows the location of the DIP switches on the bottom of the printed circuit board.

Use Switch SW4 to control the Network Line Framing and Coding
Options. Set these options to be the same as the Line Framing and Coding Options given to you by your Service Provider. If you are using two
Model 2710s together as short range modems, set both units identically.

Line Framing Options:
•
D4/Superframe:
The D4 framing format, as speciÞed in AT&T
TR62411 is the standard in which twelve frames make up a superframe. All signaling and synchronization are done in-band.
•
Extended Superframe:
Extended Superframe, as speciÞed in AT&T
TR 54016, consists of twenty-four (24) T1 frames. The framing bits are
now used for framing, CRC and the Facility Data Link (FDL). The FDL
allows maintenance messages and information to be passed between
the 2710 and the Central OfÞce.
Line Coding Options:
•
Alternate Mark Inversion (AMI):
This mode does not inherently
account for ones density. To meet this requirement, each time slot can
be reduced to 56 kbps and the Least SigniÞcant Bit (LSB) of each time
slot set to one.
•
Bipolar 8 Zero Substitution (B8ZS):
This mode assures proper bit
density in the data stream. In this mode any data pattern can be transmitted without causing ones density errors. This mode allows for 64
kbps clear channel timeslots.
Switch SW5: DS0 Channel Rate
Use Switch SW5 to set the DS0 rate.

Network Clock.
Transmitter timing is derived from the
received line signal.

Internal Clock.
Transmitter clock is derived from an internal
oscillator.
Note
When using the Model 2710 as a high-speed short range
modem, one unit of the link must be conÞgured in Internal Clock
mode, and the opposite end unit must be conÞgured for Network
Clock mode.
12
Switches SW7 and SW8: Line Build Out
Use Switches SW7 and SW8 to set the Line Build Out (LBO). The Line
Build Out varies the pulse shape and attenuation of the signal sent to the
network. The amount of Line Build Out depends on NetLink™ T1’s distance to the last repeater. The telephone company providing the service
will advise on the amount of LBO necessary.

3.2 SOFTWARE CONFIGURATION
The NetLink-T1™ features a menu-driven command system that allows
you to monitor/conÞgure its operating parameters. Follow the instructions below to conÞgure the Model 2710 using the software switches:
1. Plug the 9-pin male end of the cable to your terminal or computer’s
DB-9 serial port and start up the terminal emulator software if necessary. Plug the miniature stereo plug into the rear of the unit. The
small recessed jack on the right side of the unit is the control port
jack.
Note
If your terminal uses a DB-25 connector, please use a DB-9 to
DB-25 Adapter to connect to the cable (See Model 18PC-M).
2. Power up the terminal and set its RS-232 port as follows:
9600 Baud
8 data bits, 1 stop bit, no parity

3. Here is an example of a terminal emulator setup session. In normal
font are the various parameter types. In bold type are the values that
should be used for best results. Your terminal program’s setup
