MICROCONTROLLER FIRMWARE UPGRADE To download a new firmware from a computer to the AP microcontroller, it is necessary to have a TFTP client capable of sending a binary file. The parameters to send the firmware are: Target filename: APP Transfer mode: binary (octet) Target port: 70 Block size: 512 Note: The file to be downloaded must be the .bin (binary) image, not the hex version! File size should be 69,376 bytes. ETHERNET CONTROLLER FIRMWARE UPGRADE To download a new firmware from a computer to the AP Ethernet interface controller, it is necessary to have a TFTP client capable of sending a binary file. The parameters to send the firmware are: Target filename: X1 Transfer mode: binary (octet) Target port: 69 Block size: 512 Note: The file to be downloaded must be the .ROM (binary) image, not the hex version! File size should be 32768 or 65536 bytes. 31 C.5 Private IP networks and the Internet If your network is not connected to the Internet and there are no plans to make such a connection, you may use any IP address you wish. However, if you are not connected to the Internet and have plans to connect to the Internet, or you are connected to the Internet and want to operate your SNMP interface on an Intranet, you should use one of the following sub-networks for your network: Class A 10.x.x.x Class B 172.16.x.x Class C 192.168.0.x These network numbers have been reserved for such networks. If you have any questions about IP address assignment ask your Network Administrator. 30 Appendix C: IP Addresses, Netmask, Etc. C.1 IP Addressing An IP address is a 32-bit value, divided into four octets of eight bits each. The standard representation is four decimal numbers (in the range of 0...255), divided by dots. Example: 192.2.1.123. This is called decimal-dot notation. The IP address is divided into two parts: a network and a host part. To support different needs, three “network classes“ have been defined. Depending on the network class, the last one, two or three bytes define the host, while the remaining part defines the network. In the following text, ‘x’ stands for the host part of the IP address: Class A network IP address 1.x.x.x to 127.x.x.x Only 127 different networks of this class exist. These have a very large number of potential connected devices (up to 16777216). Example: 10.0.0.1, (network 10, host 0.0.1) Class B network IP address 128.0.x.x to 191.255.x.x These networks are used for large company networks. Every network can consist of up to 65534 devices. Example: 172.1.3.2 (network 172.1, host 3.2) Class C network IP address 192.0.0.x to 223.255.255.x These network addresses are most common. Most smaller companies’ networks are class C networks. These networks can consist of a maximum number of 254 hosts. Example: 192.7.1.9 (network 192.7.1, host 9) Class D network IP address 224.x.x.x to 239.x.x.x These addresses are used as multicast addresses. Example: 224.7.1.9 (network 224, host 7.1.9) Class E network IP address 240.x.x.x to 254.x.x.x These addresses are reserved. C.2 Network Address An address with all host bits set to "0" is used to address the network as a whole (in routing entries, for example). C.3 Broadcast Address An address with the host part bits all set to “1“ is the broadcast address, meaning “for every station.“ Network and Broadcast addresses must not be used as a host address (e.g. 192.168.0.0 identifies the entire network, 192.168.0.255 identifies the broadcast address). C.4 IP Netmask The netmask is used to divide the IP address differently from the standard defined by the classes A, B, C. By entering a netmask, it is possible to define how many bits from the IP address are to be taken as the network part and how many bits are to be taken as the host part. Standard IP Network Netmask: Class A 8 (network) 24 (host) 255.0.0.0 (mask) Class B 16 (network) 16 (host) 255.255.0.0 (mask) Class C 24 (network) 8 (host) 255.255.255.0 (mask) 29 Appendix B: Setting Auto Mute Threshold The upstream mute threshold is limited by the SNR. At lower levels, the noise level becomes closer to the signal level. Therefore, as the threshold level is dropped, the muting will start to be activated by the noise. This happens closer to the signal level when the signal is lower. The upstream noise level is proportional to the receive gain setting. With a high enough gain and a low enough mute threshold setting, the noise may be high enough to prevent the detection circuitry in the AP from muting. To ensure this does not happen, the threshold should be set no lower than 30 dB below the gain setting (i.e. Gain - 30 dB). So for gains of 36/46/56/66/76 dB, the threshold should be set no lower than 10/16/26/36/46 dBmV. This puts a lower limit on the threshold for a given gain setting. The upper limit of the threshold is based on the upstream signal level. While a setting of 45 dBmV is guaranteed to work with an output level of 45 dBmV, the signal level may change due to CATV plant gain variations. Note that upstream gain variations of the RF link have little effect since the CMTS causes the CM to compensate for upstream gain changes. So it would be recommended to set the threshold at least 3 or 4 dB below the desired output. For example, for a gain of 55 dB and an output level of 35 dBmV, the threshold should be set to between 25 (55 - 30) and 31 dBmV (35 - 4). 28 Appendix A: Specifications AP5800 Specifications DOWNSTREAM Transmit RF frequency band 5799 to 5823 MHz Transmit EIRP +15 to +28 dBm rated maximum IF input frequency range 91 to 857 MHz (channel center frequencies) IF input level range 0 to +20 dBmV per channel Downstream modulation One 6 MHz 64QAM or 25…
