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: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Murray Sent: Sunday, January 18, 2004 8:28 PM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] [ot] Grandstream hardware Hi Has anyone opened up a grandstream phone or handytone ATA to find out what is inside? What is the CPU? How much RAM?
