Configuration for 2 V.35 modems connectivity 
 

1. When two V.35 modems are used in the circuit to connect two premises, then one V.35 modem should be 

configured as LT with Internal clock mode and the other modem should be in factory default mode. 

 
2. The diagram shows the connectivity of two V.35 modems.

3. To change the clocking mode, navigate through the menus 

to configure System Clocking mode

 ( 2.1.1 of 

flowchart diagram ) and select 

change

 option. Then select 

internal

 clock mode. 

 
4. To change the DSL type, navigate through the menus 

to configure DSL Type

 ( 2.3.1 of flowchart diagram ) 

and then select 

DSL Type as LT

.  

 
5. After  performing  the  above  steps,  save  the  parameters  by  navigating  through  the  menus 

to  store 

parameters in NVRAM

 ( 2.1.7 of flowchart diagram ). 

 
6. Then restart the modem manually and verify the parameters by navigating through the menu 

to view unit 

status

. In that Clocking should be 

Internal

 and DSL Type should be 

LT

 
7. Now the modems are ready to be connected in the line.
