1.5 2361 Modem Operating At E1 Rate
While the 2361 modem is a T1 modem, it can also function in E1 mode. This can be
accomplished by changing a switch position on the Main Module. For Rackmount modems,
remove the modem from the chassis, and locate the T1/E1 switch on the board. Then, change the
switch to E1.
For a standalone modem, the switch is accessible by removing the ELIM or OLIM, reaching
inside between the ELIM and the OLIM, and toggling the switch.
