priswitch priswitch <set|get> <“switch
protocol”>
Where:
• set: Sets the PRI switch. One of the
“switch protocol” parameters is
required.
•get: Returns the current switch
protocol.
• “switch protocol”: Switch protocol
values are:
❑ att5ess
❑ att4ess
❑ norteldms
❑ ni2
❑ net5/ctr4
For E1, net5/ctr4 is the default.
Net5/ctr4 is the standard ETSI
protocol derived from ITU Q.931.
For T1, net5/ctr4 is also provided for
certain Asian countries, such as
Japan, Hong Kong, and Taiwan.
Sets or gets the PRI switch. If
more than one switch protocol is
supported, you must find out
from your telephone service
provider which protocol to
select. NET5/CTR4 is the
default. It is the standard ETSI
protocol derived from ITU
Q.931. If you change the
country settings, a new set of
PRI switch protocols is loaded.

rt rt <normal|inverted|get>
Where:
• normal: Sets the signal to normal
(rising edge receives data).
• inverted: Sets the signal to inverted
(falling edge receives data).
• get: Returns the current setting for
this option (normal or inverted).
Sets or gets the rt serial
interface control signal (receive
timing: clock) to normal or
inverted. The default setting is
“normal”.

rt inverted
rts rts <normal|inverted|get>
Where:
• normal: Sets the signal to normal
(high voltage is logic 1).
• inverted: Sets the signal to inverted
(low voltage is logic 1).
• get: Returns the current setting
(normal or inverted).
Sets or gets the rts serial
interface control signal (request
to send) to normal or inverted.
The default setting is “normal”.
