On-line Operat ions 19-15
It should be noted that pinging a SmartSwitch 1800 interface will verify only connec-
tivity to that SmartSwitch. Using the example in Figure 19-4, if the operator at device
A wants to ping device B, s/he must ping device B’s IP address.
To ping Node 1, the operator at device A must ping the IP address of interface 1. To
ping Node B, the operator must ping interface 3. To locate a connectivity problem
between A and B, the operator at device A should first ping interface 1. If a response
is received, the operator at A should then ping interface 3, then (if a response is
received) device B.

CSU/DSU Tests
To test the (optional) CSU/DSU port, the port must first be disabled. If necessary,
press
[A] at the Operations Menu (or [B], [A] from the Main Menu) to disable the port.
To run a CSU/DSU test, press [I] at the Operations Menu, then press the letter corre-
sponding to the desired test:
[A] = Self Test – transmits a test pattern to the analog portion of the circuitry and
loop the pattern back to itself.
[B] = Pattern Generation Test – transmits a PRBS (pseudo-random bit sequence)
test pattern to the remote device, which will loop the signals back.
Reloading Auxiliary Console Initialization
This operation reloads the terminal settings defined for an async terminal connected
to the SmartSwitch 1800’s Console port.
Press [E] at the Operations Menu (or [B], [E] from the Main Menu). If an async terminal
is connected the Console port, the initialization data will be sent.
