A demarcation point defines the extent of Avaya's responsibilities for a product. Beyond this point, the customer is responsible for providing overall service. Generally, Avaya is responsible for all Avaya-provided equipment.
The demarcation point for Communication Manager Messaging (CMM) server and Communication Manager are TCP/IP server ethernet ports. The customer is responsible for:
The LAN cable
The connector at the end of the cable for connection to the Communication Manager server
LAN administration not performed on the Communication Manager server and Communication Manager Messgaing
Maintaining the TCP/IP addresses and administration on the Communication Manager server after cutover, unless otherwise specified by contract
Providing the IP address, subnet mask, and gateway information for administration on the Communication Manager server
Avaya service technicians who are dispatched for messaging system installation are not responsible for troubleshooting the customer's LAN.
Avaya FAX Messaging uses the same equipment as voice messaging. The voice card ports support both voice messages and fax messages without additional cabling or hardware. As with messaging, the point of demarcation for FAX Messaging is the same as the switch integration point of demarcation.
Avaya service technicians dispatched for system installation are not responsible for troubleshooting customer fax machines.
The demarcation point for Internet Messaging is the same as that listed for LAN connectivity. In addition, the customer is responsible for:
The service agreement with an Internet service provider (ISP)
A connection to the ISP or directly with the Internet if an ISP is not used
SMTP setup
POP3 client information and setup if you are providing POP3 access as part of Internet Messaging
IMAP4 client information and setup if you are providing IMAP4 access as part of Internet Messaging
In addition, Internet Messaging can only trace delivery of a message to the trusted server, which is the last point before delivery to the ISP or Internet connection. Message status can be traced in the Messaging Logs. Given the nature of internet delivery mechanisms, a message cannot be followed between endpoints. This is a distinct difference from the digitally networked aspect of a messaging network, in which it is possible to trace the delivery of a message from origination to endpoint
