subnet mask
A subnet mask is the part of the IP address used to represent a subnetwork
within a network. A typical IP address might be 192.210.34.144. Each part of
this address is made up of eight bits. The subnet mask identifies to the RLC or
remote unit what portion of the IP address represents the network (and
subnetwork) and what portion represents the host.

switch
In a telecommunications network, a switch is the hardware that receives phone
calls and provides connections to telephone sets. The switch allows a connection
to be established as necessary and terminated when there is no longer a session
to support it.
In networks, a device that filters and forwards packets between LAN segments.
Switches operate at the data link layer (layer 2) of the OSI Reference Model and
therefore support any packet protocol. LANs that use switches to join segments
are called switched LANs or, in the case of Ethernet networks, switched
Ethernet LANs.
switch resource
A device that is configured on the switch.

TAPI

TCP/IP
Transport Control Protocol/Internet Protocol. The communication protocol used
to connect devices on the Internet. TCP/IP is the standard for transmitting data
over networks.
