For more information about configuring PPP interfaces across an asynchronous
interfaces, see the Point to Point Protocol (PPP) chapter in the Software
Reference.
Asynchronous Call Control (ACC)
You can configure the ACC module to answer calls made to a modem
connected to an asynchronous port, to validate the user making the call and to
configure the port to the mode appropriate for the desired service. Also, you
can configure ACC to originate calls by controlling a modem attached to an
asynchronous port and to switch the port to the appropriate mode once a
connection to the remote device is established.
To assign a user an IP address and MTU (Maximum Transmission Unit) for use
with an ACC call, enter the command:
set user=login-name ip=ipadd mtu=mtu
To assign an IP address and MTU to the asynchronous port accessed by the
ACC call, enter the command:
set asyn=asyn-number ip=ipadd mtu=mtu
For more information about ACC, see the Asynchronous Call Control (ACC)
chapter in the Software Reference.
Synchronous Ports
You can use the asynchronous console port on the base unit to configure the
router. Additional asynchronous ports can also connect terminals, printers and
terminal ports on host computers.
Your router supports synchronous interfaces with speeds of up to 2.048 Mbps,
also known as E1. The router will automatically generate a clock signal when a
DCE transition cable is connected to a synchronous interface (see the Hardware
Reference for details of how to construct a cable).
To set the clock speed, enter the command:
set syn=n speed=speed
For more information about synchronous interfaces, see the Interfaces chapter
in the Software Reference.
Switch Ports
A switch port is one of the physical Ethernet interfaces on the base router unit.
Each switch port is uniquely identified by a port number.
To display information about switch ports, enter the command:
show switch port[={port-list|all}]
All switch ports on the router are enabled by default. You can disable and
enable a switch port as required. To enable or disable a switch port, enter the
commands:
enable switch port={port-list|all}
disable switch port={port-list|all}
