2.2 GENERAL PRODUCT DESCRIPTION
The Model 2707RC Series are single port E1 CSU/DSUs that provide
high-speed WA N connectiv ity in a rack card p ack age. Connecting to the
serial WAN port of a switch, router or multipl exer, the NetLink-E1™ provides E1 access connection at dat a rates of 2.048 Mbps. The NetLinkE1™ is an excellent choice when terminating leased line s ervices , Frame
Relay backbones, internet access as well as LAN -to-LAN services.
The Netlink-E1™ pr ovides digit al ac cess 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 configurat ion cap abilit y via hardw are DIP switch es
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. Soft-
ware 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.

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.

S1-6 and S1-7 Clock Modes
Set switch S1-6 and S1-7 to determine the 2707RC’s transmitter timing.

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

Switch S3: DIP switch or NMS (network management system) control
The Model 2707RC can be config ured and manag ed 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.

Hardware Reset . The Model 270 7RC is set at t he fact ory for DIP switc h
control. If the us er has cha nged cont rol to NMS, and then needs to revert
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
