Re: x.25 question help
Hi! X.25 is a set of CCITT recomendations for transmitting dato over PDNs protocol suit, including OSI Layers: Physical, Datalink & Network. The speed is on Physical Layer. At the physical layer, the X.25 standard assumes an X.21 interface, but can also support V.35 and the EIA RS232-D interfaces. X.21 bis is up to 19,2 Kbps, V.35 is up to 2Mbps, and RS232 is up about 115,200 or something like this. > I have a question about x.25 transmit rate as following: > What is the maximum transmission rate for X.25? > > A. 56 Kbps > B. 64 Kbps > C. 128 Kbps > D. 1.544 Mbps > > Thanks > > dean > > > _ > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] > _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: simulating delay on Cisco routers in test bench
Hi! On Ethernet it's impossible without some kind of repeater or low-end gateways. Try to configure NT server with two Ethernet NICs on i386 computer and try to load it with many computation and bus manipulating - you'll get PROPER delay. On Serial 'clock rate' is helpful, but real satellite delay is longer. -- WBW, xander CCNP+Voice, CCIE Lab 19-20/04/2001 > At 11:06 AM 12/6/00, you wrote: > >Hi Priscilla, > > > >Is there a way to increase the round trip delay (expected delay 400ms) > >between two back to back connected CISCO routers using an IOS command. > > > >This is to simulate a satalite link delay between two CISCO routers ( > >approximately 400-600 ms) on a test bench. > > > >Appriciate your attn and response. > > > >Thanks > >msrfernando > > Hm.
