• RJ48 has a keyed connector and a notched jack. • RJ45 does not have a key or a notch. • Both have 8 pins. Although an RJ45 connector fits an RJ48 jack, the key on an RJ48 connector does not allow it to plug into an RJ45 jack. Q. I cannot get PPP to negotiate between a router set to async at a baud rate of 115200 and Hardware Flow Control on when it connects with a 3Com ISDN Impact modem. This is what is reported in the router log: WAN: scr(lcp) id xx WAN: timeout(lcp) WAN: scr(lcp) id xx WAN: timeout(lcp). A. scr(lcp) is a send config request from the router to the other side. lcp (link control protocol) is the lowest layer of PPP, and it must be established before any of the other layers, such as TCP/IP (ipcp). The router sends the configure request but does not receive an answer back from the other side, either a rcX (receive config Ack or Nack) or an rcr (receive config. request). It times out after four seconds. After it tries ten times, it disconnects and tries to connect again.
