Agenda  Quick review of value proposition  Review of Warp r1v2 hardware and software  What’s new in Warp 3.0 hardware?  What’s new in Warp 3.0 software?  Questions

Same value proposition  Fully integrated Asterisk based development platform  Both hardware and software integration handled so users can focus on added value Removes the need to source hardware components Pre-installed working software versions  Based on reliable solid state hardware  Wide range of TDM options  Small, cost effective solution targeted for SME market

Hardware

 Embedded Power PC processor  Internal flash (256Mb), RAM (256Mb), SD card  LCD  Audio in/out ports  Ethernet (100/10)  External USB  smart Fan  1 on-board FXS  Capable of 100 VoIP endpoints / 32 simultaneous G.711 conversations

Expansion Hardware  Two modules slots for TDM connectivity 1 & 2 port GSM radios 2 & 4 port ISDN BRI (4 or 8 channels) Analog trunk 4 port FXO + PFT Analog stn 4 port FXS + PFT

New hardware  NOW with some improvements; let’s review...  On-board DSP Adaptive Digital Echo Cancellation Helps offload processing from CPU G.729  Real time clock

Software

 We listened to our customers.  Here are some of the most common challenges faced on the v1 platform: Non standard OS Cross compiling (PADS) chan_pika Read only memory CPU/memory

The new platform  Standard Debian 6.0 (squeeze)  Standard Dadhi interfaces (2.5)  Fully writeable file system  Asterisk 1.8  FreePBX 2.9  Fail safe recovery mode  Package management

Software Life Cycle  Goal: to mimic PC development/deployment cycle and make easier to use  1) Getting started Box ships with pre-installed FreePBX software on on-board memory (NAND) To start developing add a SD card to the unit and transfer base software from NAND to the SD

Development Process  2) Develop Very similar to Asterisk PC development Add packages, add files, etc. Leverage 27,000 package in Debian’s repository Pika provides any missing packages Native compile environment

Useful Debian Commands  Some useful package commands: apt-get update (update list) apt-get upgrade (upgrade packages) apt-get install (install package) apt-get remove (remove package) dpkg –l (list installed packages) apt-cache (search for pkgs in repository)

Development (cont’d)  3) Evolve software Frequent Pika updates obtainable through packages (‘warp-upgrade’ or ‘apt-get upgrade’ for all S/W)  4) Ready for market Once satisfied, optimize and create a master image Copy to other SD cards Cloning is done with a Linux PC with SD card reader

Deployment  5) Deploy Plug in SD card to new Warp hardware New units will automatically detect the SD card and boot

Maintain  6) Maintain your solution Consistent with PC based solutions tarballs or deb package updates of software Remote maintenance (backup, etc.)

Fail Safe Mode  Minimal Linux image  Factory reset ability (invoked through command or detection of NAND failure)  Allows for remote unit recovery  3 boot modes: SD, NAND, failsafe  Boot preferences: SD card NAND Failsafe mode

Useful Pika commands  Some useful package commands: warp-upgrade (upgrade Pika packages) cat /proc/cmdline (running from NAND or SD?) auto_factory_defaults (invoke factory reset) failsafe (enter failsafe) bootmode set nand (boots to NAND) bootmode set SD (boots to sd)

Other notes  V1 and v2 are not compatible; modules ok  For more information –
