1.2 RADIO AND TV INTERFERENCE
The Model 2707RC 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 2707RC has been tested and found to comply
with the limits for a Class A computing device in accordance with the
specifications in Subpart B 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 2707RC 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).

2.2 GENERAL PRODUCT DESCRIPTION
The Model 2707RC Series
high-speed WAN connectivity in a rack card package. Connecting to the
serial W AN port of a switch, router or multiplexer, the NetLink-E1™ provides E1 access connection at data rates of 2.048 Mbps. The NetLinkE1™ is an excellent choice when terminating leased line services, Frame
Relay backbones, internet access as well as LAN-to-LAN services.
The Netlink-E1™ provides digital access to local WAN services between
two facilities over a dedicated 4-Wire circuit. Clock modes, line impedance, and coding options are programmed via internally accessible DIP
switches or SNMP manageable through the 1001MC. The Netlink-E1™
uses AMI and HDB3 line coding. Netlink-E1™ also supports a full range
of system and diagnostic features that make system setup easy.
The NetLink-E1 provides E1 terminations over a modular RJ-48C jack or
dual 75 Ohm BNC connectors when using the 1001RCM11575 (X.21)
rear card.

3.0 CONFIGURATION
The 2707RC features configuration capability via hardware DIP s witches
or SNMP through Patton’s Model 1001MC Management Card. This section describes all possible hardware and software switch configurations
of the network connection.
Note
The 2707RC factory default is set to DIP switch control. Software control can be enabled by setting S3 to a valid address
SNMP management station. Performing a hardware reset sets
the unit for dip switch control.
3.1 DIP SWITCH CONFIGURATION
The Model 2707RC has two eight bit 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 printed circuit board.

DIP Switches S1 and S3 can be configured as either “On” or “Off”.
Figure 2 shows the orientation of the DIP switches with respect to ON/
OFF positions. Default position and descriptions for Switches S1 and S3
are provided on the next page.

Note
If you do not have a terminal, you may force the unit to use the
DIP switches as the default configuration source by turning off
the unit, setting all the DIP switches to the ON position, then
powering on the unit. This will cause the unit to enter a special
mode. Then turn off the unit and change the switch settings to
the desired settings. When you turn the unit on again, the unit
will be set up with the selected switch settings.

Switch S1-1 through S1-8
A detailed description of each switch (S1-1 through S1-8) setting follows
the summary table below.
Table 1:
Switch Set 1 Summary

S1-1 Line Coding OFF HDB3
S1-2 Reserved OFF
S1-3 Line Build Out OFF 120 ohm
S1-4 Reserved OFF
S1-5 Reserved OFF
S1-6 Clocking Mode OFF Network
S1-7 Clocking Mode OFF Network

Switch S1-1: Line Coding
Use switch S1-1 to control the network line coding. Set these options to
be the same as the line coding given to you by your service provider. If

you are using two Model 2707s together as short-range modems, set
both units to HDB3.

Switch S1-3: Line Build-out Impedance
Switch S1-3 is used to select line build-out (LBO) impedance for the Model
2707’s E1 port. Your Model 2707RC comes equipped with either an RJ-48C
connector, dual BNC connectors, or both. When connecting to the E1 network, the LBO selection must match the connector type. If the dual BNC connectors are used, the line build-out impedance must be set to 75-ohm.
Otherwise, for the RJ-48C connector , impedance should be set to 120 ohm.
Table 3:
S1-3 Line Build-out settings

75 ohm On
120 ohm Off
S1-6 and S1-7 Clock Modes
Set switch S1-6 and S1-7 to determine the 2707RC’s transmitter timing.
Table 4:
S1-6 and S1-7 Clock Modes
S1-6 S1-7 Clock Mode
On On Network (Received Recovered)

Network Clock Transmitter timing is derived using the received
line signal (received recovered) from the network.
Internal Clock Transmitter timing is deriv ed from an internal clock
source.
External Clock Transmitter timing is derived from DTE terminal
timing. (Units equipped with 10Base-T modules do
not operate in external clock mode. They enter
internal clock mode when this setting is selected.)

Switch S1-8: Loopback tests
Use switch S1-8 to allow the Model 2707RC to enter loopbact test mode
when the DTE raises the appropriate loop request pin.

Switch S3: DIP switc h or NMS (netw ork management system) contr ol
The Model 2707RC can be configured and managed via DIP switches, or
NMS-SNMP/HTTP through a Patton Model 1001MC management card
acting as a proxy agent. (refer to the 1001MC user manual when using
this mode). Switch S3 selects control and management mode for the
Model 2707RC.

The Model 2707RC is set at the factory for DIP switch
control. If the user has changed control to NMS , and then needs to re vert
to DIP switch control, use the following procedure:
1. Pull the Model 2707RC out of the rack.
2. Set all switches (S1 and S3) to the ON position.
3. Install the card into the rack and power up the unit.
4. Pull the card out again and change the switches to the desired set-
tings. The unit is now under DIP switch control.
5. Install the card back into the rack.
NMS Control.
When switches S3-1 to S3-8 are set to a setting other
than the ones shown in Table 6, the Model 2707RC enters NMS control.
While under NMS control, each of the Model 2707RC cards housed in a
rack must have an address. Table 7 and Figure 3 show examples of
address settings. The table follows the hexadecimal system, where
switch SW3-1 is the least significant bit (LSB), and SW3-8 is the most
