Switch S1-5: Anti-Stream Timer
The anti-stream timer protects multidrop networks from a drop that
is continuously transmitting. If the DTE keeps RTS raised for more
than the Time Value in seconds, the timer forces RTS off internally.
This allows the rest of the multidrop network to resume operation. The
CSU/DSU remains in the forced-off condition until the terminal drops
RTS. Use Switch S1-5 to enable the timer.
Timer Value in Sec at Various Line Rates
S1-5 Timer 56 19.2 9.6 4.8 2.4
On Disabled not applicable
Off Enabled 2 4 8 15 30
Switch S1-6: Data Format
Use Switch S1-6 to configure the Model 2530 for synchronous or
asynchronous connection to the DTE.
S1-6 Setting
Off Synchronous
On Asynchronous
Switch S1-7: Asynchronous Character Length
Set Switch S1-7 to configure the total number of asynchronous
bits per asynchronous character (when Switch S1-6 is set to “On”).
S1-7 Setting
Off 10 bits
On 11 bits
NOTE: The total asynchronous character is determined by sum of
all start bits, data bits, stop bits and parity bits. For instance:
1 start bit + 8 data bits + 1 stop bit + 0 parity bits = 10
bits

Switch S1-8: Extended Signaling Rate
Use S1-8 to configure the frequency tolerence the Model 2530
“looks for” in asynchronous data rates (i.e., the actual variance from a
given frequency level the Model 2530 Series will tolerate).
S1-8 Setting
Off -2.5% to +1%
On -2.5% to +2.3%
3.1.2 DIP Switch Set “S2”
The DIP switches on set S2 may be used to configure the line
rate, clock mode, force RTS, and DSR status during local loop. Default
settings and detailed descriptions for each switch in the set are shown
below.
Switches S2-1, S2-2 and S2-3: Line Rate
Use Switches S2-1, S2-2, and S2-3 to configure the signalling rate
on the line (RJ-48S port). The setting should match the speed of your
digital service.
S2-1 S2-2 S2-3 Line Rate
On On On 2.4 kbps
On On Off 4.8 kbps
On Off On 9.6 kbps
On Off Off 19.2 kbps
Off On On 56 kbps
Off On Off 64 kbps
Off Off Off Forces configuration
