6.12 8AS Cable

An 8AS cable is connected to an 8AS interface card to commission or maintain the 8AS interface
card.
Introduction
An 8AS cable connects the console port on an 8AS interface card to the serial port of an operation
terminal. You can use shield cables or unshielded cables as required in different scenarios.
The common usage scenarios of 8AS cables are:

To connect an 8AS interface card to automatic teller machines in a bank, use shield straight-
through cables. You can buy shield straight-through cables from Huawei or made these
cables onsite.
To connect an 8AS interface card to a dumb terminal, use a transit cable and a shield
straight-through cable. A transit cable has an RJ45 plug on one end and an RJ45 socket on
the other end. The transit cable converts the pin assignments on the dumb terminal to the
standard pin assignments, which are the same as those on the straight-through cable. Then
the straight-through cable can connect to the dumb terminal.
To connect an 8AS interface card to a serial port device, such as a PC or modem, use an
asynchronous serial cable and a transit cable. One end of an asynchronous serial cable is
an RJ45 socket, and the other end has a DB25 plug and a DB9 plug. The asynchronous
serial cable connects to the PC or modem through the transit cable.
NOTE
Huawei can customize 8AS cables of specified length.
