Configuring ASMi-52 

ASMi-52 Ver. 2.5 

 

To configure the master clock: 
•  From the System Configuration menu (Main Menu > Configuration > System 

Configuration > Master Clock), configure the central ASMi-52 clock to 

external or internal and remote ASMi-52 clock to the receive clock. 

 

To configure the SHDSL interface: 
•  From the SHDSL Configuration menu (Main Menu > Configuration > Port 

Configuration > SHDSL Configuration), configure the following SHDSL 
parameters: 

 

SHDSL compatibility 

 

Power backoff 

 

Snext margin, if line probing is set to adaptive 

 

Current margin, if line probing is set to adaptive 

 

Power spectral density (for ASMi-52 with 2-wire line interface and line 

probing set to fixed) 

 

Line probing 

 

Line type (for 4-wire ASMi-52 units only) 

 

Loop attenuation threshold 

 

SNR margin threshold. 

ASMi-52 includes a serial, E1, T1, or 10/100BaseT DTE interface configured as a 

single interface. ASMi-52 can be multiplexed as i.e., E1 + Serial DTE interface, or 
E1 + 10/100BaseT DTE interface, or Serial + 10/100BaseT DTE interface, in 
which case each pair of interface has to be configured separately. 

 

To configure the serial interface: 
•  From the DTE Port Configuration (Main Menu > Configuration > Port 

Configuration > DTE Configuration), select the required data rate. 

When configuring an E1 interface, you have to select the modem’s framing mode 
and assign each E1 timeslot to carry data or idle code.  
If in your application, an ASMi-52 unit with an E1 interface operates opposite 
another ASMi-52 unit, the E1 settings of the remote device are automatically 
matched to those of the local modem (the Units Identical Setting value is set to YES 
by default). The Units Identical Setting value of the local modem overrides the 
management commands of the remote supervisory terminal.
