2.2 GENERAL PRODUCT DESCRIPTION

The Model 2707RC Series are single port E1 CSU/DSUs that provide

high-speed WAN connectivity in a rack card package. Connecting to the

serial WAN port of a switch, router or multiplexer, the NetLink-E1™ pro-

vides E1 access connection at data rates of 2.048 Mbps. The NetLink-

E1™ 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 imped-

ance, 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 switches

or SNMP through Patton’s Model 1001MC Management Card. This sec-

tion 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 configura-

tion 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.

Figure 1. Model 2707RC Series top view, showing location of DIP switches.

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.

Figure 2. Close up of DIP switches showing ON/OFF positions.

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.

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 net-

work, the LBO selection must match the connector type. If the dual BNC con-

nectors 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 Transmitter timing is derived 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 switch or NMS (network management system) control

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.

Hardware Reset . The Model 2707RC isset at the factory for DIP switch

control. If the user has changed control 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
