Configuring the E1 or T1 Trunk Card
2.3 Configuring the E1 or T1 Trunk Card
This section describes how to configure E1 or T1 trunk cards.
These procedures are designed for E1 or T1 cards that are shipped pre-configured
in a system. To configure E1 or T1 cards that are shipped as configured or
unconfigured replacements, refer to the GSM Field Maintenance Guide
.
Your system is shipped from the manufacturer configured with the correct cards
for your site-specific application. These can be 75 Ohm E1, 120 Ohm E1 or
100 Ohm T1 cards. All cards are shipped with the appropriate connectors.
Table 2-7 lists the cards and the procedures that apply to each card type.
Cable runs of greater than 600 meters (1968 feet) are not
supported directly from the card. If you are attempting a longer
cable run between UltraWAVE chassis please contact Customer
Service to determine if you need a repeater for your application.
