26.1 Description
The 6NR/6NV module can be used wherever
synchronous bandwidth greater than a single DS0
is required. This is typically referred to as frac-
tional T1/E1.
Typical devices you can connect to the module
include:
• Current differential protective relaying
pilot channel
•Ethernet LAN through externally
connected router or switch
•Video surveilance
When a 6NR or 6NV module is set to N=1, it is
fully compatible with previous generation 64R
and 64V modules.
26.2 Connection
Connections are made through the 25-pin
interface connector. Please refer to Fig. 26-1 for
the pinout.
26.3 Installation
As with other FOCUS modules, we recommend
that you initially install and test the 6NR or 6NV
module and interface in a “test” chassis (i.e., one
that is not part of an operating network). This way,
you can quickly perform the acceptance test
without interfering with a live network. Whether
you are installing the module in a test chassis or a
chassis that is on line in a network, use the instal-
lation procedure described here.
The 6NR/6NV module occupies one chassis slot
and one or more time slots (DS0s), depending on
the N value. Before installing the module and its
interface, make sure that:
• The FOCUS chassis is set up, energized,
and operational, with all necessary
common equipment (see Chapter 3)
• The FOCUS Configuration Software (FCS
version 3.10 or greater) has been installed
on your computer (see Chapter 3)
• Acceptance tests for the FOCUS chassis
and all previously installed equipment have
been done to rule out invalid test results for
this module
• FCS is up and running (see the FCS online
help facility: FOCUS Configuration
Software > Starting FCS)
26.3.1 Hardware Installation and
Connections
To install the 6NR/6NV module and interface,
complete the following steps.
1. Bring the FOCUS chassis “on line”.
Click on the “Online” speed button
.
This uploads to the FCS the current status,
settings, operating statistics, etc., for the
FOCUS chassis.
2. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Setup
menu or click on the “Unlock FOCUS
Chassis” speed button . Then respond to
the“Enter password” dialog box with
“focus1”.
This puts the chassis into a configurable state.
