Table 3-207: +MPING Command Parameters (Cont.)

<Parameter>	Description
<TTL>	Time To Live (TTL). Specifies number of hops (hop is
	one step, from one router to the next, on the path of a
	datagram on an IP network), which the Echo Request
	message may be routed over. The value is set by using
	TTL field in IP header. Valid value range is from 1 to
	255.
	Default value: 64
<TOS>	The Type Of Service (TOS) is for internet service
	quality selection. The type of service is specified along
	the abstract parameters precedence, delay, throughput,
	and reliability. These abstract parameters are to be
	mapped into the actual service parameters of the
	particular networks the datagram traverses. Minimum
	and maximum values for TOS are 0 and 255
	respectively. Refer to RFC 791 and RFC 2474 which
	obsoletes RFC 791 for TOS defined values.
	Default value: 0
<TimeOut>	Specifies the amount of time, in milliseconds, to wait
	for the Echo Reply message that corresponds to a sent
	Echo Request message, measured after Echo Request
	message was sent. If the Echo Reply message is not
	received within the time-out, +MPINGSTAT
	unsolicited response, with <status> equal to 1, will be
	sent to DTE. Valid value range is from 500 ms to
	600,000 ms (10 minutes).
	Default value: 4000
