Cisco Internet Service Node (ISN) Product Description
OL-1250-03
Chapter 2      ISN Solution Components
Non-ISN Cisco Products
Provides the called point’s network address resolution for the calling point through ARQ/ACF 
messages upon the calling endpoint’s request, if both called and calling points are registered to the 
same Gatekeeper.
Provides the called point’s network address resolution for the calling point through LRQ/LCF 
messages upon the calling endpoint’s request, if the called point is registered in another Gatekeeper.
Supports BRQ/BRJ/BCF messages for bandwidth control. (This might be based on bandwidth 
management or be a null function which accepts all requests for bandwidth changes).
Note
At the time of software release, ISN Version 2.1 had been tested with and is supported on Cisco 36XX, 
26XX and 37XX Gatekeepers running IOS Version 12.3 (3). For the most current information, see the 
Cisco Internet Service Node (ISN) Data Sheet
 on Cisco Connection Online (CCO) at

Gatekeeper Failover
ISN 2.1 utilizes the Hot Standby Router Protocol (HSRP) method of failover. 
HSRP is a Cisco-proprietary routing protocol that provides backup to a gatekeeper in the event of failure. 
Using HSRP, several gatekeepers work together to present the appearance of a single virtual router on 
the LAN. The gatekepers share the same IP and MAC addresses. Therefore, in the event of failure of one 
gatekeeper, the hosts on the LAN are able to continue forwarding packets to a consistent IP and MAC 
address. The Gatekeeper automatically transfers routing responsibilities from one device to another. ISN 
Voice Browser, during failure, transfers over to an alternate Gatekeeper automatically, and no transfers 
are lost.
Note
HSRP is the only method of failover provided by ISN. ISN 2.1 does not support Gatekeeper clustering.
User Tasks
Configure two gatekeepers as part of an HSRP group, assigning a virtual IP address to this group.
Set the gatekeeper in the ISN Voice Browser to point to the virtual IP address of the HSRP group.
IPCC
The Cisco IPCC delivers an integrated suite of proven products that combine Cisco IP telephony and 
contact center solutions. 
The design and features of ISN Version 2.1 enable it to function as a network or premise based IVR 
and/or queue point for IPCC. 
Automated Speech Recognition (ASR) and Text-to-speech (TTS)
Automatic Speech Recognition is the ability to provide speaker independent voice recognition to gather 
information from a caller. Text-to-speech signifies the ability to convert a text string to speech to play 
for a caller.
