P RI Primary Rate Interface. HDB3 based multi-channel ISDN interface. T1 PRI (US, Japan) supports up to 23
channels (1472kbps), while E1 (Europe, rest of world) supports up to 30 channels (1920kbps).
P seudo- W ire An emulation of a synchronous connection over a Packet Switched Network.
P STN Public Switched Telephone Network. The world's telephone network, including analogue and digital
connections, plus mobile telephony.
QoS Quality of Service. A method of prioritising Ethernet/IP traffic.
Remote A unit connected to a system, but not Local to the user.
Routing Passing a call or communication from a Source to a Destination, usually using a Call Routing Profile on
Patapsco devices.
RSTP Rapid Spanning Tree Protocol. A protocol designed for using physical backup connections in an IP/Ethernet
system without causing loops.
RTP Real-time Transport Protocol. An IP based protocol used for real-time streaming applications, usually audio
and video.
Rx Receive.
Schedule With Patapsco devices, certain functions can be set to happen only at certain times, for example Call
Routing Profiles can be set to only be active at certain times of day.
SF P Small Form-factor Pluggable. A compact, hot-pluggable transceiver which can be used to interface with
different media such as optical fibre and copper ethernet.
SIP Session Initiation Protocol. A communications protocol used by Patapsco ISDNoIP products to set up calls.
Call Routing configuration can also be centralized by using a SIP server to handle all traffic.
SN MP Simple Network Management Protocol. Used to configure and monitor devices in a system. Patapsco devices
currently support SNMP event reporting in the form of Traps and Alarms.
Source The port or group of ports where a call will enter the Patapsco device. Can also be a Logical Link number for
some products.
SP ID Service Profile Identifier. A code used by North American ISDN BRI (ANSI) connections to initiate
communications between devices.
Subaddress An extra set of numbering used in ISDN calls to denote extra information and activate additional routing.
Subnet Mask Subnetting is used to split an IP/Ethernet network used by many devices into smaller sections to reduce the
amount of delay, routing/processing time and also packet collisions for devices in the network. A Subnet
Mask is configured on a device to define which section the device is part of.
Switch Type T1 switches use slightly different Switch Types. Each one causes a routed call to have its Number Type and
Number Plan defaulted to a certain value.
T1 1472kbps (up to 23 x 64kbps timeslots) HDB3 based protocol. Common in North America and Japan.
TCP Transmission Control Protocol. A point-to-point tunneling IP-based protocol. Guarantees high integrity
communications rather than lossy, high-speed communications.
TDM Time Division Multiplexing. The system of splitting a data connection into separate timeslots for different data
streams. The streams are multiplexed together to use a single communication link, and can be demuxed at
their destination.
TE Terminal Equipment. The interface type of a synchronous network connection. If the device is to connect to a
network or another device, that network/device must have an NT interface (see NT).
TE I Terminal End-point Identifier. An identifier given to each call processed on an ISDN interface. The TEI is
