 +====== Telsey CPA-ZNTE60T ======
 +ADSL Wireless Voice Gateway, series CPVA642.
 +Some Fastweb HAGs (italian broadband provider) have this hardware.
  
 +===== Supported Versions =====
 +Supported, but without ADSL.
 +  * Attitude Adjustment (12.09):\\ [[http://​downloads.openwrt.org/​attitude_adjustment/​12.09/​brcm63xx/​generic/​openwrt-CPA-ZNTE60T-squashfs-cfe.bin|openwrt-CPA-ZNTE60T-squashfs-cfe.bin]]

 +===== Hardware Highlights =====
 +^ CPU ^ Ram ^ Flash ^ Network ^ USB ^ Serial ^ JTag ^ Other ^
 +| BCM96358 | 32MiB | 8MiB | 4 x 1| Yes | Yes | Yes | ADSL |
 +
 +===== Installation =====
 +
 +Initial installation can be done from the stock firmware web interface, or from the CFE web interface. ​ Unfortunately installation via TFTP seems to have been disabled for this device.
 +
 +One important note is that the CPVA642 models have a dual image setup. ​ That means if an image fails to boot, the system will fall back to the other image installed, for the stock firmware. ​ We don't actually want this, because it means that if you flash via the CFE web interface when there is already a good image, the image will not be written to the start of flash but to a point 4MB from the start (i.e. as if there were two 4MB images). ​ This confuses OpenWRT.  ​
 +
 +That means if you have a successfully flash image and you want to flash via the CFE web interface, you need to erase everthing except the bootloader first.

 +**Note:** This will void your warranty!
 +
 +  *To remove the top cover there are 3 screws hidden under the rubber feet
 +  *There are two screws holding the PCB to the bottom cover.

 +==== Serial ====
 +
 +Serial port is marked in the picture: on the right of the switch chip BCM5325 find two soldered holes enclosed in squares. The left one, above R707 is Receive data, the right above R706 is Transmit. Level 3V.
 +Gnd is the hole near c809, +3Vcc is the hole near C313
 +
 +==== JTAG ====
 +
 +How to connect to JTAG interface, and how to reflash the device with [[http://​downloads.openwrt.org/​tools/​oem/​jtag/​tools.zip|JTAG tools]]
 +
 +See [[doc:​hardware:​port.jtag]] for more JTAG details.
 +
 +==== Failsafe mode ====
 +If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt'​s failsafe mode.
 +
 +=== Boot into failsafe mode ===
 +  * Unplug the router'​s power cord.
 +  * Connect the router'​s LAN1 port directly to your PC.
 +  * Configure your PC with a static IP address between 192.168.1.2 and 192.168.1.254. E. g. 192.168.1.2 (gateway and DNS is not required).
 +  * Plug the power in.  The Power LED will light up
 +  * Wait for the Power LED to start flashing
 +  * As soon as the Power LED is flashing immediately press Reset and a few times .
 +  * If done right the Power LED will quickly flash 3 times every second.
 +  * You should be able to telnet to the router at 192.168.1.1 now (no username and password)
 +
 +=== What to do in failsafe mode? ===
 +**NOTE:** The root file system in failsafe mode is the SquashFS partition mounted in readonly mode. To switch to the normal writable root file system run mount_root and make any changes. Run mount_root now.
 +
 +  - Forgot/lost your password and you like to set a new one
 + ​passwd
 +  - Forgot the routers IP address
 + uci get network.lan.ipaddr
 +  - You accidentally run 'ipkg upgrade'​ or filled up the flash by installing to big packages (clean the JFFS2 partition and start over)
 + mtd -r erase rootfs_data
 +If you are done with failsafe mode power cycle the router and boot in normal mode.
 +
 +==== Buttons ====
 +The CPA has two buttons. They are Reset and Wireless Setup. The buttons can be used with hotplug events. E. g. [#​wifitoggle WiFi toggle].
 +^ BUTTON ^ Event ^
 +| Reset | reset | 
 +| Wireless Protected Setup | wps |
