Switch S1-8: Response to Remote Loop Request
Use Switch S1-8 to allow the Model 1092ARC to enter the Remote
Digital Loopback diagnostic test when requested to do so by the far end
modem. For example, when Switch S1-8 is set to “ON”, it will enter
RDL mode (See Section 5.2.2) when requested to do so by the remote
modem.

3.1.3 Configuration Switch Set “S2” - Management Port Address
If the address is 0 (all ON positions ON S2), then the unit will run
completely from its' dip-switch configuration. This can be useful for
testing circuits independently of the management system.
In order to use the SNMP or control port management, an address
is required. If an address is placed on the switch, the unit will boot from
its stored flash configuration. It begins looking for POLL commands
from the Model 1001MC (SNMP management mode).
Switch S2 allows an 7 bit address to be assigned to a link. The
following rules apply to setting the address. Bit S2-1 is the least
significant bit. A bit set to "ON" is considered a "0". A bit set to "OFF" is
considered a "1". Patton Electronics suggests that you set your
addresses starting with address 1 at the far left of your rack (farthest
away from the power supplies) and increment the numbers by one as
you go from left to right. Setting the addresses in this manner will make
configuration easier as you start using the web page management. An
example of this is shown in table A-1.

Switches S1-4: Management Setting
When setting the SNMP Management, the DTE rate switches (S1-
1, S1-2, and S2-1) are also needed to be at the ON position. Therefore,
to set a 1092A unit SNMP management mode, the following switches
have to be at the ON position, S1-1, S1-2, S2-1, and S1-4.
Use Switch S1-4 to configure the 1092ARC’s management setting.
