Setting the LAN Rate in a Multiplexer Unit
The maximum multiplexer rate is 2048 kbps (general rate). The sum of the data
rate of two interfaces should not exceed 2048 kbps.
For example:
• IR (DTE Serial) Interface + LAN – If IR or the DTE Serial Interface works at
1024 kbps, then LAN cannot work at a speed of more than 1024 kbps
because the sum of both interfaces cannot exceed 2048 kbps.
ASMi-52 has a multiplexer modem with two interfaces. The maximum rate for
LAN is:
• If LAN + E1, then the LAN maximum rate =
2048 kbps – used TSs (timeslots) x 64 kbps
• If LAN + IR (DTE Serial) Interface, then the LAN maximum rate =
2048 kbps – DTE rate
Configuring Autonegotiation
ASMi-52 autonegotiation allows you to operate at the fastest data rate available.
With autonegotiation enabled, the ASMi-52 unit automatically determines
between itself and the DTE the fastest data rate and duplex mode that they can
operate. With autonegotiation disabled, the LAN interface of ASMi-52 operates at
the speed and duplex mode that is configured by the Default type.
To set autonegotiation:
1. From the Local LAN Configuration menu, select Autonegotiation (Main menu
> Configuration > LAN Configuration > Local LAN Configuration >
Autonegotiation).
Toggle between Enable and Disable.
