Extron IP Intercom System Frequently Asked Questions

Extron IP Intercom System

General

1. Is the IP Intercom System a VoIP system?

Yes. By definition, Voice over Internet Protocol (VoIP) is a technology that transmits voice

communication over a data network, i.e., the Internet or a corporate network. Extron's IP Intercom

System is not compatible with IP Telephony systems.

2. Is the IP Intercom System compatible with IP Telephony systems?

Extron's IP Intercom System is not compatible with IP Telephony systems. IP Telephony systems offer

the ability to carry telephone signals over a data network instead of the traditional POTS network. IP

Telephony is also a VoIP system, but it uses other protocols such as H.323 or SIP defined by the

International Telecommunications Union Telecommunication Standardization Sector (ITU-T) to manage

the communication between handsets. IP Telephony systems provide two-way, full-duplex

communications while the IP Intercom is two-way, half-duplex.

3. Which products will the IPI 101 AAP and IPI 104 APP Intercom Modules work with?

The IP Intercom Modules will only work with IP Intercom-enabled MLC 226 IP MediaLink Controllers

shipped after November 16, 2005. These controllers have an RJ-45 connector on the back panel labeled

"Intercom."

4. Can the IPI 101 AAP or IPI 104 AAP be used without an MLC 226 IP?

No. The bulk of the intercom processing capability resides in the MLC 226 IP, not the IPI modules.

5. How do I know if my MLC 226 IP will work with the IPI 101 AAP and IPI 104 AAP?

It will work if the MLC 226 IP has the intercom RJ-45 and audio output connector. All controllers

shipped after November 16, 2005 with an engineering revision number of E16076 or later are

compatible with the IP Intercom System.

6. Is there a trade-in program that would allow me to trade my older MLC 226 IP for one that

supports the IP Intercom System?

This is taken on a case-by-case basis. Contact the Extron S3 Sales and Technical Support Hotline for

details.

7. How many locations can the IP Intercom Modules communicate with?

The IPI 101 AAP will communicate with one location; the IPI 104 AAP will communicate with four

locations.

8. What type of warranty do the IP Intercom Modules and MLC 226 IP MediaLink Controller

products carry?

As with all powered products, Extron offers a three-year limited warranty on parts and labor for the IP

Intercom Modules and MLC 226 IP MediaLink Controllers.

Network

1. Are IP Intercom communications secure in any way?

Communications are encoded but not encrypted. Audio must be encoded in order to get from point A to

B in the system. This product is intended for support applications and not for secure, confidential audio

communications.

2. Is the IP Intercom compatible with all networks?

The IP Intercom System can be integrated on all Ethernet-based networks. Sound reproduction and the

quality of various other functionalities will vary depending on your network infrastructure and available

bandwidth. Please contact the Extron S3 Sales and Technical Support Hotline for more information.

3. How much network bandwidth does the IP Intercom System utilize when communicating?

An average 80 kbps (kilobits per second) of bandwidth is used for each unicast communication between

two IP Intercom Modules or between an IP Intercom Module and the help desk. When making
