Description: The line build out or line length specification for
the DS1 or DSX-1 transmitter. These values are card
specific:

10 port DSX-1 card
------------------
The accepted values are:

1  -   0 to 110 feet
2  - 110 to 220 feet
3  - 220 to 330 feet
4  - 330 to 440 feet
5  - 440 to 550 feet
6  - 550 to 660 feet
7  - over 655 feet

1-port and 4-port T1 cards
--------------------------
The accepted values are:

 96  -   0 to 133 feet
128  - 133 to 266 feet
160  - 266 to 399 feet
192  - 399 to 533 feet
224  - 533 to 655 feet
96   -  0 db
32   - -7.5 db
64   - -15 db

4-port CBR card
---------------
The accepted values are:
        
96   -  0 db
32   - -7.5 db
64   - -15 db

4-port Short Haul T1 cards
--------------------------
The accepted values are:
 96  -   0 to 133 feet
128  - 133 to 266 feet
160  - 266 to 399 feet
192  - 399 to 533 feet
224  - 533 to 655 feet

What is pportDs1LineBuildout?

This sets the line build-out (cable-length compensation) for this DS1/DSX-1 transmitter, chosen from a card-specific table of foot-ranges; for example, on the 10-port DSX-1 card, values 1 through 7 correspond to 0-110 feet up through over 655 feet. Because DSX-1 signal levels must be tuned to the actual cable run length to avoid over- or under-driving the line, setting this wrong on this specific port causes pulse-shape distortion that shows up as bit errors that look like a bad cable even when the cable itself is fine. A DSX-1 run of about 300 feet from this port to the cross-connect would call for build-out value 3 (220-330 feet) on the 10-port card.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.13
snmpwalk -v2c -c public <target> CASCADE-MIB::pportDs1LineBuildout

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.13.1
snmpget -v2c -c public <target> CASCADE-MIB::pportDs1LineBuildout.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.13.1 i <value>
