PollCat NetLink-VIP & PollCat NLJ-VIP - User’s Guide
18.2. Telnet Pass-Through
The Telnet Pass-Through function allows users to communicate directly
with devices connected to PBX Port A, PBX Port B, the AUX Port, the
PBX IP Port, the Console Port, or the Modem Port. All VIP menu functions
are disabled, and the only VIP command that will be recognized is ^B30
(Exit Pass-Through and Disconnect Telnet Session). In addition, data can
be sent using either Standard Telnet Protocol or Raw Socket Mode.
When a Telnet connection is established, using the Telnet Pass-through
option, the following events will occur:
1. Upon connection, the VIP will send the "POLLCAT NETLINK"
message (and the site ID, if deﬁned) and then wait for a password.
2. If a valid password is entered, the VIP will send the "READY"
message, and will then allow communication with the device
connected to the speciﬁed port.
