The following illustration shows the pinouts for the analog voice switching daughtercard 
(VSA) 8-pin, RJ-11 jacks used to connect the voice ports on the card to voice devices in the 
VoIP network that support analog connections, e.g., telephone and fax machine.

There are no DIMMs on the VSA, only DSPs on the FXS or FXO grand-daughtercards with a 
maximum of one channel per port. For more information on the DSPs, see Digital Signal 
Processors (DSPs), DIMMs and Available Channels on page 2-4 for more details.

Although VSA cards do not contain a Deadman switch, similar PSTN fallback call protection 
can be provided in the event of a power failure simply by plugging the analog VoIP switch 
into an Uninterruptable Power Supply (UPS). For a description of the Deadman switch on the 
digital voice switching daughtercards, see VSD Deadman Switch on page 2-8.

There are no Cross-Over type toggle switches on the VSA daughtercards. For a description of 
the Cross-Over toggle switches on the digital voice switching daughtercards, see VSD Cross-
Over Toggle Switch on page 2-9, and VSB NT (LT)/TE Cross-Over Toggle Switch on page 2-13.
