| Demarcation Points
> ## 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. When installing an INTUITY system, you must be aware of the demarcation points for: Switches not maintained by Avaya Local area network (LAN) connectivity for Message Manager or supported email applications INTUITY FAX Messaging INTUITY Internet Messaging email #### Demarcation Points for Switches Not Maintained by Avaya Avaya service technicians dispatched for INTUITY system installation are not responsible for making any connections directly to switches not maintained by Avaya.
> Note: Avaya recommends joint acceptance testing for systems integrated with switches that are not maintained by Avaya.
> The demarcation points for the integration of switches not maintained by Avaya vary by integration type as shown in the following table.
> Switch Configuration | Demarcation point
> --- | ---
> Serial without a switch integration device (SID) or a translator | Immediately following the null modem
> Serial with a SID or a translator | Immediately following the SID, the translator, or the 202T modem (as applicable)
> In-band | Immediately before the modular connectors
> Digital station interface without a SID | The end of the Avaya-provided connector cables
> Digital station interface with a SID | Immediately following the SID
For additional information concerning the extent of the installation, see the contract between the customer and Avaya. #### Demarcation Point for LAN Connectivity The demarcation point for the Avaya INTUITY TCP/IP is the point of connection into the LAN circuit card. The customer is responsible for: The LAN cable The connector at the end of the cable for connection to the Avaya INTUITY system LAN administration not performed on the Avaya INTUITY system Maintaining the TCP/IP addresses and administration on the Avaya INTUITY system after cutover, unless otherwise specified by contract Providing the IP address, subnet mask, and gateway information for administration on the Avaya INTUITY system Avaya service technicians dispatched for Avaya INTUITY system installation are not responsible for troubleshooting the customer's LAN. #### Demarcation Point for INTUITY FAX Messaging Avaya INTUITY FAX Messaging uses the same equipment as INTUITY voice messaging. The voice card ports support both voice messages and fax messages without additional cabling or hardware. As with INTUITY AUDIX, the point of demarcation for Avaya INTUITY FAX Messaging is the same as the switch integration point of demarcation. Avaya service technicians dispatched for Avaya INTUITY system installation are not responsible for troubleshooting customer fax machines. #### Demarcation Point for INTUITY Internet Messaging 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 POP3 client information and setup if you are providing POP3 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 an INTUITY AUDIX network, in which it is possible to trace the delivery of a message from origination to endpoint. Top of page
