 NMS ISDN for Natural Call Control Developer's Manual (6407-21): NFAS and D Channel Backup
The D channel to use as the backup is specified in the configuration file.
A similar situation may arise when at the moment of the primary D channel failure both sides are in the Connected state and their states are preserved, but then one side initiates the disconnect process and is cleared before the data link is reestablished.
Since a channel cannot serve as a B channel while designated as a backup D channel, an application is not allowed to place a call on a timeslot on a primary or backup D channel.

 [No title]
Taking into account the impact of a transmitter and receiver clock jitter, channel skew and cross talk, the BER of an interface, power supply noise, device process, temperature, as well as EMI, then a practical data speed limitation can be derived from the minimum bit time and a specified eye diagram margin.
In the case of a multi-channel, the channel and package skew are an important contribution to the timing margin.
The channel and package skew can be as long as 140ps in some cases.

 ISDN D channel handler (USH0000586)
The D channel is used for packet data and for telephone signalling and supervision at a bit rate of sixteen kilobits per second.
It directs D channel data to a receive buffer storage location where it is accessible by a translator.
Packet data received in the D channel is recognized after it has been stored in the receive buffer storage location and then is immediately queued for transmission via the frame processor and a digital transmission link to a separate packet network.

When the SMS channel is configured as per SMS Channel Configuration, one or more host names will be associated with the channel.
The SMS channel is set up the same for both one-way and two-way functionality, with the exceptions noted in the topic Configuring the SMS Channel for Two-Way SMS.
Note also that the time before a channel change takes effect can differ depending on what the change is. Many channel option changes take effect in all channels started since the change was made, which may seem almost instantaneous since the Job Controller is often starting new channels.
