Hi Has anyone opened up a grandstream phone or handytone ATA to find out what is inside? What is the CPU? How much RAM? Cheers Rob
I'm not sure, I just opened mine up to see. Looks like they epoxied over three of the chips. One is a 73pin, another is a 44 pin, and the last looks to be a 44 pin. Ethernet is a RTL8019AS (10mbit) and it's using a Tamarack TC3097-8 repeater (HUB) which actually supports 9 ports (8 ethernet, 1 AUI). Obviously this is only a 10mbit repeater. It's worth noting that this chip is end of life. Figure a couple bucks for these if you can get them, sounds like old stock to me. Flash memory looks to be about 8m according to the 29LV800ABTC-70 flash ram chip. These are going for under $1, sounds like more old stock. The Xilinx XC9536XL CPLD could be the processor and RAM... It's around $2 Anyway, I'm not a hardware guy but that's what I see. On another note, what's the deal with Hold, Mute, Caller ID Review, and Called Number Review on these things? Do they just not work, or am I missing something? -Bill -----Original Message----- From: asterisk-users-admin@lists.digium.com [mailto:asterisk-users-admin@lists.digium.com] On Behalf Of Robert Murray Sent: Sunday, January 18, 2004 8:28 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] [ot] Grandstream hardware Hi Has anyone opened up a grandstream phone or handytone ATA to find out what is inside?

Yes. Check the mailing list archives. On Sun, 2004-01-18 at 19:28, Robert Murray wrote:> Hi > > Has anyone opened up a grandstream phone or handytone ATA to find out what is inside? What is the CPU?

This kind of card would provide hardware assisted DSP functions as well as patent indemnification. Would you even have to USE the DPSs in order to be patent indemnified?
