New Motorola IP telephony reference platform features Linux support
Mar 24, 2003 — by LinuxDevices Staff — from the LinuxDevices Archive — 3 viewsMotorola announced a new Voice Over IP (VoIP) reference platform for developing media gateway devices including remote access servers (RAS) and IP-PBXs. The new platform, called the “Smart Packet Telephony 8101,” is said to support IP-based voice, fax, and modem data services.
The reference design is based on a combination of Motorola's MPC8260 PowerQUICC II processor combined with six MSC8101 DSPs (see block diagram, below). The design includes a pair of Fast Ethernet (10/100 Mbps) ports and has onboard expansion for PICMG PCI Telecom Mezannine Card (PTMC) form-factor daughter cards. An included DSP PTMC card supplies the six MSC8101 DSPs, and Motorola said a future PTMC card with StarCore DSPs is also planned, among others. Other hardware features of the platform include: 4 E1/T1 interfaces for up to 128 PSTN or PBX DS-0s; 4 POTS ports for up to 4 analog POTS lines or trunks; H.100 connection; a Utopia level-2 interface capable of bit rates of up to 155 Mb/s; an RS-232 craft or management port; and a JTAG debug port. Schematics of the reference platform boards are provided, Motorola said.

The platform includes support for voice compression, echo cancellation, dual-tone multiple frequency (DTMF) detection, voice activity detection, silence suppression, and well as modem and fax data modulation and demodulation, Motorola said.
The platform's development environment is the “CodeWarrior Development Studio for Packet Telephony,” from Motorola's Metrowerks software tools subsidiary. Driver libraries for the MPC8260 processor and MSC8101 DSPs are included, along with a bootloader (for the MPC8260) and board-level diagnostics for the platform. Metrowerks also supplies a Linux-based operating system that supports the platform, and support software for media gateway and remote access server functions is available from various third-party vendors.
The new VoIP reference platform will be available starting in June 2003 from Metrowerks, the company said.
