Lucent Technologies 5ESS User Manual

(99-5E-8582). Both features are dependent on the base SIP feature
(99-5E-8382).
The SIP without Encapsulated ISUP feature (99-5E-8587) is
dependent on the base SIP feature (99-5E-8382). The SIP without
Encapsulated ISUP feature is transport independent.
The SIP Enhancements to Support PSTN Gateway Phase 1
(99-5E-8658) is dependent on the base SIP feature (99-5E-8382).
The DRM IP Trunking (99-5E-8645) is dependent on the base SIP
feature (99-5E-8382).
Inter-operability
One of the main objectives of SIP is to provide call signaling and call
control independent of the IP network technology.
Inter-operability with IP equipment
The IP router or Layer 2 (L2) switch to which the 5ESS
®
switch
protocol handlers (PHs) interface can be from any vendor, provided
that it meets the requirements of the Session Initiation Protocol (SIP)
- Interface Specification, 235-900-344 document.
The IP network components and the 5ESS
®
switch can be configured
many different ways. The different configurations are described in “IP
Router & Layer 2 Switch Interoperability” (2-15).
Inter-operability with other Switching Systems
SIP for Packet Trunking is based on standards for the protocol layers
including SIP, SCTP, and/or UDP, IP, and ICMP, and the software is
intended to operate with other vendors. However, this feature works
best when used with other 5ESS
®
switches. If another vendor’s switch
adheres to the standards in the same way, the products should be
compatible. No assumptions are made about inter-operability with
other vendor’s equipment.
The Session Initiation Protocol (SIP) - Interface Specification,
235-900-344 document explains the interface implementation in
greater detail.
Customer Security
It is the customer’s responsibility to ensure the security of the IP
backbone network. It is assumed that the IP layer security is
performed by the edge router and that the 5ESS
®
switch is in a trusted
network.
