3.0 PPP OPERATIONAL BACKGROUND PPP is a protocol used for multi-plexed transport over a pointto-point link. PPP operates on all full duplex media, and is a symmetric peer-to-peer protocol, which can be broken into three main components: 1. A standard method to encapsulate datagrams over serial links; 2. A Link Control Protocol (LCP) to establish, configure, and test the data-link connection; 3. A family of Network Control Protocols (NCPs) to establish and configure different network layer protocols.
4.0 INSTALLATION 4.3 POWER CONNECTION The 2121/2135C is equipped with Network, DTE, and power interfaces. This section briefly describes connnection to each interface. ply. 4.1 CONNECT TO 10BASET ETHERNET PORT 4.3.1 AC Power Supply (100-240VAC) The shielded RJ-45 Ethernet port on the Model 2121/2135C is designed to connect directly to a 10BaseT network. Figure 3 shows the 10BaseT RJ-45 port pin description. You may make connections up to 300 feet using type 4 or 5 cable.
4.3.2 DC Power Power-up 2121 via DB-15 Connector on Pin 15 Supply DC power directly to the power supply jack. DC power supplied must be +5VDC ±5%, 500mA minimum, center positive, and can be supplied via a barrel type plug with 2.1/5.5/10mm I.D./O.D./Shaft Length dimensions. For this powering option, set J3 to position 7 and 8 as shown in figure 4 (factory default). Place strap position 1 and 2 on J3 for DC power supply. See figure 6 below.
5.0 CONFIGURATION All configuration is done through software auto-detection for the Model 2121/2135C. Once you have configured your mux or other equipment to be connected to the 2121/2135C, the unit is ready for operation. Observe that the serial port of the 2121/2135C is configured as a DTE and must connect to a DCE. The LAN port also requires no configuration to connect to a 10BaseT Ethernet. Note: The X.21 and V.35 Interface is configured as a DTE.
TXD RXD CTRL IND STAT CLK PWR Figure 9. Front of Model 2121, showing LED Indicators TXD- Trasmit data LED (green) blinks to indicate data transitions and remains OFF when no data is transmitted (idle). RXD- Received data LED (green) blinks to indicate data transitions and remains OFF when no data is received (idle). CTRL- Control LED (yellow)- turns ON at power up to indicate to the DCE that the 2121 is active.
