2.2 GENERAL PRODUCT DESCRIPTION
The
NetLink-T1™
Model 2710RC Series are single port T1/FT1
CSU/DSUs that provide high-speed WAN connectivity in a rack card
package. Plugging directly into the serial 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-toLAN services.
The Netlink-T1™ provides digital access to a local WAN service
provider or directly between two facilities over a dedicated 4-Wire circuit. WAN bandwidth, framing and coding options are programmed via
internally accessible DIP switches or via a VT-100 type terminal using
a Model 1001CC control card. With a 1001CC card, a terminal can
manage addressable 2710RC cards using menu driven controls. 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.
The NetLink-T1™ provides T1 terminations over a modular RJ-48C
jack and comply with jitter tolerance capabilities as specified in ANSI
T1.403 and AT&T TR62411. Power options include a single AC or DC
or redundant AC/DC.
3.0 CONFIGURATION
The Model 2710RC features configuration capability via hardware
DIP 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 2710RC has two eight bit DIP switches and two rotary
DIP switches that allow configuration for a wide range of applications.
The switches are accessed by removing the card from the chassis.
Figure 1 shows the location of the DIP switches on the top of the board.
DIP switches S1 and S2 can be configured as “On” or “Off”. Figure
2 shows the ON/OFF positions orientation of the DIP switches. Default
position and descriptions for S1 and S2 are provided on the next page.

FRONT RS-530
NOTE:
The Model 2710RC is shipped in switch configuration mode.If you need to
access the software configuration menu, a Patton Model 101CC proxy card is needed.
The 1001CC is installed in the Model 1001 Patton Rack and can manage all 2710RC
cards in the rack.(See section 3.3 for more information on software configuration.)
To change the 2710RC from sofware to switch configuration, you need to perform a hardware reset on the 2710RC.A hardware reset is done by setting all S1 switches to the ON
position, power the 2710RC on (insert card on a live 1001 rack), wait for five seconds, pull
the card out and set S1 switches to the desired settings, reinsert card in the rack.

two Model 2710RCs together as short range modems, set both units
identically.
S1-4 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 (ESF): Extended Superframe, as speci-
fied 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 2710RC
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 S2-2: Tx Clock Select
Switch S2-2 selects the clock that is used to accept the Transmit
Data from the DTE interface. Standard DTE interfaces will transmit
data with respect to the External Clock. In some cases a DTE interface
will transmit with respect to the Transmit clock sent out from the
2710RC. Please review the information provided with your DTE equipment for more information on its' operation. In most cases when there
are errors on the line only in the direction of the transmit data either
S2-2 or S2-3 can be changed to solve the problem.
S2-2 Tx Clock Select
On Transmit data accept with respect to the transmit
clock from the 2710RC
Off Transmit data accept with respect to the external
clock from the DTE (not valid when unit uses an
Ethernet rear card)
Switch S2-3: Tx Clock Invert
Switch S2-3 allows the user to invert the transmit clock originating
in the 2710RC. When S2-2 is set for transmit clock, it may be necessary to invert the transmit clock to allow for cable delays.
S2-3 Tx Clock Invert
On Transmit clock is inverted
Off Transmit clock is normal
Switches S2-4 and S2-5: Line Build Out
Use Switches S2-4 and S2-5 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.
