4. 40 A typical router will have a minimum delay that is between 1 and 2 fields Suppose a crosspoint command is received just before a vertical field mark The software may be able to prepare the crosspoint data and send it to the hardware when that vertical field mark occurs but the hardware itself typically has a one field delay in it so the soonest that such a crosspoint would switch would be one field plus a little from when it was received If the command were received towards the beginning of a field rather than the end of a field the delay would be closer to two fields Industry parlance is to call this a one field delay because only full fields of delay are counted The delayfields argument of this command takes into account the hardware delay So if a router has a minimum delay including the hardware delay of one full field as described in the previous paragraph then a delayfields value of 1 causes this minimum delay to be used A delayfields value of 0 will also cause this minimum delay because the router uses its minimum if a smaller value is specified A delayfields value of 2 however will add one more field to the minimum possible delay Thus delayfields specifies the number of full fields of delay between end of crosspoint command string received and crosspoint switch occurs Note that the actual minimum value of delayfields depends on the particular router model Routers typically have a limit to the number of cross

No special character marks the start of these strings they simply begin at the appropriate point within the command The G command on the other hand uses the tilde character to mark both the start and end of a character string argument Just before the router begins executing a command string it sends a leader to the host the same number as are required in commands from the host As it executes the commands some of them may generate additional output back to the host These command response characters are always preceded and followed by a space character making the response string easily human readable After the command string has been executed the routing switcher returns the string OK with a single space character before and after the word OK followed by the trailer and a CR carriage return ASCII 0D character to the host This indicates that the command has executed successfully If an error occurs within any command of a command string the remainder of the command string is ignored and the router returns the string ERROR followed by an optional descriptive string followed by a string of trailer characters and a CR character to the host An error can be caused by an unknown command name or bad arguments to a command GENERIC PROTOCOL The simplest possible command string would be which consists of the leader and trailer characters but no commands between them This command string would gen
