8AS (8-Port-Asynchronous WAN Interface Card)

Card Overview

The 8AS is a high-speed asynchronous serial interface module and working in protocol or flow mode. It can connect to the PSTN through a modem or function as a serial port server to implement remote management for terminals.

An 8AS card can be installed in a WSIC slot of a router.

Figure 7-111 shows the appearance of an 8AS card.

Functions and Features

Table 7-254 describes the functions and features of an 8AS card.

Table 7-254 Functions and features

Function and Feature	Description
Asynchronous serial interface	Connects to the PSTN through a modem or functions as a serial port server to implement remote management for terminals.
Basic functions	Functions as a dialup access server for small- and medium- sized ISPs when asynchronous serial interfaces are used for dialup.
Basic functions	Supports redirection to other devices when the asynchronous serial interface functions as a serial port server.
Interface rate	Supports a maximum of 115.2 kbit/s transmission rate for each asynchronous serial interface.
Protocols supported	Supports the PPP and IP protocols in protocol mode. Does not support the PPP or IP protocol in flow mode.

Table 7-255 Indicator description

Number	Indicator	Color	Description
1	STAT	Green	Slow blinking: The system is running properly. Fast blinking: The system is being powered on or restarting.
		Red	Steady on: A fault that affects services has occurred and cannot be rectified automatically. The fault needs to be rectified manually.
		Off	Off: The software is not running or is being reset.
2	LINK (interface status indicator)	Green	Steady on: A link has been established.
2	LINK (interface status indicator)	Green	Off: No link is established.

Attribute	Description
Connector type	RJ45
Standards compliance and working mode	RS232
Minimum baud rate	600 bit/s
Maximum baud rate	115.2 kbit/s
Function	Modem dial-up Backup Asynchronous leased line Terminal access
Cable type	8AS Cable
