Provides non-intrusive bridging jack access to (IN) and from (OUT) the HDSL2 span at the DSX-1
interface. Allows the two DS1 payloads to be monitored.
Provides bidirectional communication between the unit and an external terminal to allow
configuration and performance monitoring through the Maintenance Terminal screens.
Provides the human-readable Common Language Equipment Identifier (CLEI) code number and
the Equipment Catalog Item (ECI) bar code number.
For some products the configuration number may contain either a standalone two or three-digit
configuration number or a five or six-digit warranty configuration number as follows:
Digit 1 - Last digit of shipment year
Digits 2 and 3 - Shipment month
Digits 4, 5, and 6 - Configuration number
The configuration number identifies the version of the product. New configuration numbers usually
accompany changes in the last two characters of the CLEI code.
The configuration number is also found on a small label attached to the unit. It is the last two
numbers (following the x) of a 13-character part number. For example: 150-1234-01-x01.
