NORWOOD, MASS. Mapletree Networks Inc. has launched a palm-sized module that can support a 30-port E1 line, with the ports dynamically allocatable among voice, data and fax network traffic.
Dubbed the MTN1030, the module delivers four times the port density and half the power consumption of its nearest competitor, the company said, and is "the only network-access subsystem that provides true universal port functionality-the only one that can dynamically detect and process any type of network access connection data, fax, voice, VoIP, FoIP, VoDSL and wireless on any port," said Ali Bigdeliazari, chief technology officer and vice president of marketing.
The module is based on the company's UniPorte architecture, which Bigdeliazari called "a new approach to designing convergence network-access equipment that maximizes port density, flexibility and scalability while minimizing power consumption. Unlike conventional network access architectures, in which entire subsystems must be preconfigured to perform a particular function, the UniPorte architecture enables each port to dynamically configure itself to accommodate any type of incoming call," he said.
"Moreover, because the UniPorte architecture is fully programmable, new functions can be added through software changes without affecting existing functions. This flexibility makes it easy for carrier class OEMs to develop convergence network access equipment that can provide a broad range of services, can readily adapt to changing usage patterns, and be readily upgraded to support new services without requiring forklift upgrades," he noted.
The module provides an "out-of-the-box solution for a wide range of analog modem, fax, VoIP, FoIP, wireless and VoDSL/VTOA services," he said. Data modem support includes V.90, V.34 and lower data modulations, together with NP5 and V.42bis compression, and MNP 2-4 and ITI-T V.42 error correction. Fax support includes ITU-T V.17, V.29, V.27ter, T-30, Class 2 and Class 2.0 fax modulations. Voice support includes ITU G.711, G.723.1, G.729A, and G.729B voice coders, G.165 and G.168 echo cancellation, voice activity detection, comfort noise generation, DTMF relay, jitter buffer management and playback, call status/progress monitoring, statistics/error collection, and system diagnostics.
Packetization support includes PPP and SLIP data, RTP packets for VoIP, T.38 IFP packets for FoIP, and rate-adaptation with buffering, spooling and stalling. VoDSL support includes ITU I.366.2 and I.363.2 loop emulation and trunking for VTOA gateways. Wireless support includes PIAFS, a cellular protocol primarily used in Japan and South East Asia. Support for other wireless features such as GSM and TFO (Tandem-free operation) is in the works.
The module uses a proprietary time-division multiplexed bus to acquire and process DS-0 channels from external network-interface devices such as E1/PRI cards. The module also provides an electrical PCI interface with full bus-mastering capability. "This enables easy connection to the host system and efficient transmission of packetized data to and from the host processor's local memory," Bigdeliazari said. The module will be available this quarter, priced at less than $30 per port.
