The Megaplex-104 and Megaplex-204 are cost-effective channel banks designed specifically for small point-of-presence (POP) applications. They have one E1 uplink and can support up to eight or 16 FXS voice channels, respectively. The channels support various analog voice features that are required for voice services providers.

Each FXS port supports caller ID, loop-start signaling, reverse polarity and 12 kHz/16 kHz metering pulse, thereby meeting the specifications for public payphones.
