3.0 CONFIGURATION

The Model 2710 features configuration capability via hardware
switches or a software control port. This section describes all possible
hardware and software switch configurations of the NetLink-T1™.

3.1 DIP SWITCH CONFIGURATION

The Model 2710 has eight internal DIP switches that allow configu­ration 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.

The Model 2710 DIP switches (Switches SW1 - SW8) can be con­figured as either “On” or “Off”. Figure 2 (below) shows the orientation
of the DIP switches with respect to ON/OFF positions.

Default positions for Switches SW1-SW8 are shown in the table on

Switch SW4: Line Framing and Coding

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.

SW4 Line Framing & Coding

Off ESF/B8ZS
On D4/AMI

Line Framing Options:

D4/Superframe

: The D4 framing format, as specified in AT&T
TR62411 is the standard in which twelve frames make up a
superframe. All signaling and synchronization are done in­band.

Extended Superframe: Extended Superframe, as specified in

AT&TTR 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 Office.

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 Significant 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.

Switch SW6: Clock Mode

Set Switch SW6 to determine the 2710’s transmitter timing.
SW6 Clock Mode

Off

Network Clock

. Transmitter timing is

derived from the received line signal.

On

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 configured in Internal Clock
mode, and the opposite end unit must be configured for Network
Clock mode.

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.
