www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] 4.2. Basic Communications Basic Communications are accomplished through two sub-types: • Broadcast - By default, XStream Modems communicate through Broadcast communications and within a peer-to-peer network topology. When any modem transmits, all other modems within range will receive the data and pass it directly to their host device.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] 4.2.2. Repeater Mode Characteristics: Self-organizing - No route configuration is necessary Self-healing / Fault-tolerant Low power consumption and Minimized interference Network throughput is determined by number of hops, not by number of repeaters. Multiple repeaters within range of source node count as one hop. Supports “transparent” multi-drop mode or addressed data filtering mode.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] Repeater Network Configuration A network may consist of End Nodes (EN), End/Repeater Nodes (ERN) and a Base Node (BN). The base node initiates all communications. The repeater network can be configured to operate using Basic Broadcast or Basic Addressed communications.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] Response packet delay As a packet propagates through the repeater network, if any node receives the data and generates a quick response, the response needs to be delayed so as not to collide with subsequent retransmissions of the original packet.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] 4.3. Acknowledged Communications 4.3.1. Acknowledged Mode Characteristics: Reliable delivery through positive acknowledgements for each packet Throughput, latency and jitter vary depending on the quality of the channel and the strength of the signal. Recommended Use: Acknowledge Mode configuration is appropriate when reliable delivery is required between modems.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] After receiving and acknowledging a packet, the receiving modem will move to the next frequency and listen for either a retransmission or new data for a specific period of time. Even if the transmitting modem has indicated that it has no more pending transmit data, it may have not received the previous ACK, and so it may retransmit the packet (potentially with no delay after the ACK slot).
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] 4.3.2. Multi-Streaming Mode Characteristics: Enables exclusive connections [Definition is in Theory of Operation section.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] Initiating a Connection Connection Guidelines: • A remote modem can only request a connection with the base modem. • The base modem may hold off or grant a connection request to another modem. • A remote modem will not try to establish a connection if one already exists. • A connection fails if no response is received after RR (Retries) CRP packets.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] Configuration AT Command Mode AT command mode is used for all commands on base and remote modems. Binary command mode is not available when MD = 1 or 2. The base is in AT command mode when not engaged in an exclusive connection with a remote. No AT Command Mode sequence is needed. When a base modem is connected to a remote modem, the AT Command Mode sequence is used to enter AT command mode.
www.agelectronica.com www.agelectronica.com XStream‐PKG‐T™ Telephone RF Modem – Product Manual v5.x00 [2006.02.24] Sleep Modes and Connections Cyclic sleep can be used with the remote modems to conserve power.
