Channalized DS3 Quick Start


ImageStream's PCI-921-CDS card is a channalized DS3 WAN adapter which can individually address all of the DS0s and T1s in a DS3.

Configure the PCI-921-CDS to access the individual T1's

1.) First configure the channelized DS3 WAN interface, including any DS3 specific options your provider specified.
!
interface Serial0
 description CDS3 Interface
 service-module ds3 clock source external
 service-module Frame Type M23
!
2.) Configure new hardware sub-interfaces for each channelized circuit being terminated by the PCI-921-CDS WAN adapter. Each hardware sub-interface will need to reference which channels of the DS3 it should utilize though the use of the service-module ds3 timeslots command. Channels can be referenced by the individual DS0's or by T1 circuits.

This configuration will assign the first T1 channel on the channilized DS3 to hardware sub-interface Serial0-1.

interface Serial0-1
 service-module ds3 timeslots t1 1
 encapsulation hdlc
 ip address 192.168.1.1 255.255.255.252

This configuration will assign DS0's 0 through 23 on the channilized DS3 to hardware sub-interface Serial0-1.

Channalized DS3 command syntax

DS3 hardware interface commands:

debug [1-9]
-- Sets debug log level
loopback
-- Enables local loopback on DS3
transport DS3 [CBIT|M13]
-- Select DS3 Framing mode Cbit parity or M13
service-module ds3 lbo
-- Set the internal CSU.s line buildout. Use only if the cable between your card.s TX connector to the demarcation point is greater than 225 feet
service-module ds3 egl
-- Set the internal CSU's Rx equalization on
service-module ds3 receive-equalization
-- Same as egl option. Set the internal CSU's Rx equalization on
service-module ds3 transmit-all-ones
-- Diagnostic feature, card transmits a continuous stream of one on the line.
service-module ds3 clock source [internal|line [NUM]]
-- Select the clock source. Line defaults to 1, NUM defines which T1 to use for timing
