service provider
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your NonStop S-series server. OSM and TSM
allow you to use the help of a service provider by configuring client software to support
remote notification and remote access.
service specific connection oriented protocols (SSCOP). An adaptation layer protocol
defined in ITU-T Specification: Q.2110.
Shared Millicode Library. An intrinsic library containing privileged or TNS-derived millicode
routines used by many native-compiled programs and by emulated TNS programs.
This library includes efficient string-move operations, TNS floating point emulation, and
various privileged-only operations. These routines are mode-independent; they comply
with native calling conventions but can be directly invoked from any mode without
changing execution modes.
shared run-time library (SRL). A collection of procedures whose code and data can be
loaded and executed only at a specific assigned virtual memory address (the same
address in all processes). SRLs use direct addressing and do not have run-time
resolution of links to and from the main program and other independent libraries.
Contrast with dynamic-link library (DLL). See also TNS shared run-time library (TNS
SRL) and TNS/R native shared run-time library (TNS/R native SRL).
Signaling ATM Adaptation Layer (SAAL). This resides between the ATM layer and the
Q.2931 function. The SAAL provides reliable transport of Q.2931 messages between
Q.2931 entities (for example, ATM switch and host) over the ATM layer; two sublayers:
common part and service specific part.
Simple Network Management Protocol (SNMP). An asynchronous request-response
protocol used for network management. SNMP originated as a means for managing
Transmission Control Protocol/Internet Protocol (TCP/IP) and Ethernet networks. OSM
and TSM packages can include an SNMP-compliant interface for communication
between the system console and NonStop S-series server.
slot. A physical, labeled space for a customer-replaceable unit (CRU) or field-replaceable
unit (FRU) that is part of a module. A module contains one or more slots.
slot location. A three-number identifier for a particular slot on a system that consists of the
group number, module number, and slot number. EXAMPLE: 02,01,08 (group 02,
module 01, slot 08).
SLSA subsystem. See ServerNet LAN systems access (SLSA) subsystem.
SNMP. See Simple Network Management Protocol (SNMP).
SONET. See Synchronous Optical Network (SONET).
SP. See service processor (SP).
