Configuring the Ultra-WAN CSU/DSU Interfaces 57
Before beginning any of the procedures in this section, complete the
following tasks:
■
Attach a RJ-48C cable between the Ultra-WAN CSU/DSU interface
and an appropriate telco switch or external CSU.
■
Log on to the system with Network Manager privileges.
Configuring a
CSU/DSU Interface
for ISDN PRI Dial
Service
This section describes how to configure Ultra-WAN CSU/DSU interface for
ISDN PRI dial service.
To configure the Ultra-WAN CSU/DSU interface, follow these steps:
1 Set the FrameMode as appropriate for your setup:
SETDefault !<path> -PAth FrameMode = T1_SF | T1_ESF | E1_CRC4 |
E1_NOCRC
where <path> = 4A, 4B, 4C, or 4D.
The FrameMode parameter allows you to specify the frame mode. The
allowable values are the following:
2 Set the connector type as appropriate for your setup using:
SETDefault !<path> -PAth CONNector = E1_Pri |T1_Pri
where <path> = 4A, 4B, 4C, or 4D.
3 Set the Switch Type as appropriate for your setup using:
SETDefault !<path> -PAth SwitchType = ETSI | ATT5ESS | ATT4ESS |
DMS100 | DMS250 | NTT | NI2
The SwitchType parameter specifies the type of switch to which your
ISDN line is connected.
4 Set the LineEncoding as appropriate for your setup using:
SETDefault !<path> -PAth LineENCoding = B8ZS | AMI | HDB3
where <path> = 4A, 4B, 4C, or 4D.
The LineENCoding parameter specifies the transmission encoding
method for a serial line. The coding method you specify for the serial line
T1_SF Superframe format T1.
T1_ESF Extended Superframe format T1.
E1_CRC4 CRC-active E1.
E1_NOCRC E1 without an active CRC.
