Note When setting the 1082 for SNMP Management, the DTE rate switches (S1-1,S1-2, and S2-1) must be also set to the ON posi- tion. Therefore, to set a 1082 unit SNMP Mangagement mode, the following switches have to be at the ON position, S1-1, S1-2, S2-1.
Switches S1-1 and S1-2: Data Rate
Use switches S1-1 and S1-2 to configure the asynchronous or synchro- nous data rate of the Model 1082 and Model 1082/144. Each setting rep- resents one synchronous data rate and one asynchronous data rate.
S1-1 | S1-2 | Sync Data Rate | Async. Data Rate |
| | | |
On | On | 32 kbps | Reserved |
Off | On | 56 kbps | Reserved |
| | | |
On | Off | 64 kbps | Reserved |
| | | |
Off | Off | 128 kbps (see note) | 0–38.4 kbps |
| | | |
Off | Off | 144 kbps or 19.2 kbps (see note) | Reserved |
| | | |
Note The Model 1082 can also operate at the 19.2 kbps synchronous rate, and the Model 1092/144 can also operate at the 144 kbps synchronous rate. To operate at these rates, set switches S1-1 and S1-2 both to the OFF position and Switch S2-1 to the ON position (see section , “Configuring DIP switch S2” on page 122 for a description of Switch S2-1).
If the S2-1 switch is positioned in the OFF position, the 128 kbps sync data rate/0–38.4 kbps async data rate option is selected.
Switch S1-3: Data Set Ready during Line Loopback Test
Use Switch S1-3 to control the behavior of the DSR signal at the EIA interface during the line loopback test.
S1-3 | Setting |
| |
On | DSR is on during local line loop |
Off | DSR is off during local line loop |
