Command Reference Guide Global Configuration Mode Command Set61200510L1-35E Copyright © 2005 ADTRAN 379data-call [mtu | multilink]Use the data-call commands to set the pre-authentication defaults for maximum transmit unit (MTU) sizeor to enable multilink for inbound demand routing calls. Use the no form of each command to return to thefactory default settings. See the mtu on page 198 for more detailed syntax descriptions.Syntax Descriptionmtu Sets the maximum size for the transmit unit. Valid range: 64 to 1520.multilink Enables the negotiation of multilink MRU size for inbound calls.Default ValuesBy default, the MTU size is 1500 and multilink is disabled.Applicable PlatformsThis command applies to the NetVanta 1000R, 3000, 4000, and 5000 Series units.Command HistoryRelease 11.1 Command was introduced.Functional NotesThere are certain PPP parameters that must be known before PPP can negotiate an inbound call whenusing demand routing. To ensure PPP convergence, it is recommended (in most cases) that demandrouting interfaces use the same settings as those specified in the data-call commands. The data-call mtu command sets the MTU and controls the negotiated maximum receive unit (MRU) size duringincoming calls for link control protocol (LCP) negotiation. If the PPP parameters do not match theauthenticated user, the link is renegotiated.Usage ExamplesThe following example specifies an MTU of 1200 on the demand routing interface:(config)#data-call MTU 1200The following example enables multilink for inbound demand routing calls:(config)#data-call multilink
