To query analog backplane relay(s) specified on Channel 2 of Slot 2 for switching
aspects:
abusList = channel.getbackplane("2002")
Queries for the closed channels indicated by the scope of the channel list parameter.
closed = channel.getclose(ch_list)
ch_list: A string representing the scope of closed items being queried. Items can
include channels, backplane relays, and channel patterns.
closed: A string listing the channels that are currently closed.
The returned string will list the channels or channel patterns closed. If more than one
channel or channel pattern is closed then, they will be comma delimited in the string. If
ch_list equals ―slotX‖ where X is 1 to 6, the response indicates the channels that are
closed on that specific slot only and no channel pattern information is provided.
Likewise, if ch_list equals ―allslots‖ then, the response indicates all channels that are
closed within the system. For channels the format will be SCCC (MUX channels) or
SRCC (matrix channels). When the channel list contains a channel pattern, only the
channels in that image which are closed will be returned.
If a single slot is being queried and that slot is empty or does not support the close
channel concept then, the response will be an empty string meaning no channels are
closed on that slot. This allows you to use ―allslots‖ to query for all channels closed and
not worry about an error if one of the slots is empty or does not support close channels.
The ch_list parameter indicates the scope of channels affected and may include:

allslots or slotX (where X equals 1 to 6).

channel ranges or individual channels or channel patterns

analog backplane relays.
If nothing is closed within the specified scope then, a nil response will be returned.
An error will be generated if:

Syntax error in parameter string.

An empty parameter string.
