1 General

1.1 Document Purpose

This document provides general, installation and testing information for the Ethernet Router (RTR) cards

shown in Figure1 and Figure2. This document covers models 3641-80 and 3648-80.

1.2 Document Status

This document reissued to add information regarding the 3648-80 8-port router.

1.3 Equipment Function

The routers are part of the 360-80 Intelligent Channel Bank (ICB). They can function as a router or as a

bridge between the Ethernet port and the T1/E1 transport. They allow point-to-point connection between

two Ethernet IP networks using Point-to-Point Protocol over HDLC (PPPoH) or Frame Relay. The only

differences between the 3641-80 and the 3648-80 is that the 3648-80 has an unmanaged Ethernet switch

designed into the card to eliminate the need of an external hub or switch and does not support E1

applications. Since both units are similar, they will be referred to as ‘the router’ in this document.

1.4 Equipment Location/Mounting

The router plugs into one of the full size slots of the Charles Industries 360-80 ICB shelf and one

controller unit must be installed in the shelf for the unit to operate. The 360-80 routers require an issue 2

or later 3603-81 T1-S Controller with software version v3.1/fpga10 or higher. The 3641-80 one port

router will operate with the issue 1 3603-81 E1-S controller. The Controller GUI or craft terminal can be

used to verify the software for the controller. If the GUI based Network Management System (NMS) is

used, the NMS version must be version v3.5/v5.2 or higher. If the SNMP based Network Node Manager is

used, the MIB must be version 4.4 or higher. See T1 Controller NMS management or craft terminal

practices to for procedure to verify software versions.

If upgrading of the T1-S Controller is required, files are included on the CD shipped with the router unit.

To upgrade the 3603-81 T1-S Controller software, see the 3603-81 T1-S Controller Software Upgrade

Procedure on the CD. To upgrade the NMS version, delete the old software in the ‘Charles’ directory from

the PC and then automatically load the new software from the CD by executing the ‘Setup.exe’ file. The

files are located in CD directory under /T1-S Controller Upgrade Software and MIB/NMS3.5_IADmgmt5.2.

To upgrade the SNMP MIB, delete the old MIB and load the new MIB (filename – CharlesIADmib-

rv4.4.my) from the CD.

1.6 General Description

The router card provides a point-to-point connection between Ethernet IP networks over a T1/E1. The T1

connection can be set to any rate from 56 Kbps (1 timeslot set to 56 Kbps) to 1.536 Mbps (24 timeslots

set to 64 Kbps) with the T1 controller or to 1.920 Mbs (30 timeslots set to 64 Kbps with the E1-S

controller). With the E1 controller, the unit can use from 1 to 30 timeslots at a rate of 56 or 64 Kbps for the

used timeslots. The assigned timeslots used must be contiguous. The timeslot allocation is done through

a management port on the T1/E1-S Controller unit. See T1/E1-S Controller unit documentation for

additional information.
