| DescriptionIn one mode of operation, the MX25 is a stand alone SIP to PSTN gateway. When operating in this mode, theMX25 converts the format of a phone call to allow it to pass between the IP network and the publictelephone network. The MX25 is also capable of operating as a system that extends the functionsof the MX250 to a branch office with 25 or fewer users. In this configuration, the MX25communicates with the MX250 and exchanges information regarding users and devices. Evenwhen there is a failure in the WAN link connecting the MX250 and the MX25, the MX25 continuesto operate and allows for incoming and outgoing calls to the PSTN.
Telephony
There are three slots in the MX25 which allow for the insertion of plug in modules. These modulesprovide connections to devices such as phones and fax machines, and connection to the PSTN. Forconnecting to analog phones and fax machines, an FXS module is used. For connecting to thePSTN using analog, an FXO module is used. For connecting to the PSTN using ISDN BRA, a BRIS/T module is used. Both Japanese ISDN and ETSI ISDN are supported on the BRA interface. AnMX25 can accomodate any combination of these cards. For connecting to the PSTN using T1 or E1,a T1/E1 module is provided. Only one of these cards can be inserted into an MX25 and only oneT1 or E1 circuit can be used. For T1, the protocol can be CAS or ISDN. The CAS protocolssupported include Loop Start, Ground Start, Immediate Start, and E&M Wink Start. The ISDNprotocols supported include Lucent Custom, Nortel Custom, US National, and INS1500. For E1, theprotocol is ETSI ISDN
