Service Channels Provisioning Options
Service channels at both ends of a hop (and end-to-end in a link) must
be provisioned the same.
Service channel provisioning is interactive. When an option is selected for any service
channel, that option is excluded from selections on the other applicable service channels.
Provisioning options for Service Channels 1, 2, and 3 are listed:
• Service Channel 1 (64 kb/s channel) – can be used to carry 4-wire audio, RS-232 data,
or MCS-11 fault alarm information.
•AUDIO 1 and 2 – Two audio provisioning options (AUDIO 1 and AUDIO 2) are pro-
vided for Service Channel 1. Each audio channel is a 4-wire audio channel that pro-
vides off-hook detection, level control, and E and M-lead signaling. AUDIO 1 also
has DTMF decoding that allows a specific station to be dialed. External connection
to AUDIO 1 is J316. External connection to AUDIO 2 is J317.
•RS-232-1 – RS-232 Channel 1 is an RS-232 formatted data channel that can pro-
vide interface to an external computer/modem. External connection to RS-232-1 is
J312.
• MCS-11 – The MCS-11 channel is an RS-422 formatted data that provides an
interface to an external MCS-11 Monitor and Control System or TSM system (used
to control multiple MCS-11 systems). External connections to the MCS-11 include
J307, J308, J309 and J310.
• Service channel 2 (64 kb/s channel) – can be used to carry 4-wire audio, RS-232 data, or
MCS-11 fault alarm information.
•AUDIO-1 and -2 – Same as Service Channel 1
• RS-232-2 – RS-232 Channel 2 is an RS-232 formatted data channel that can pro-
vide interface to an external computer/modem. External connection to RS-232-2 is
J313.
• MCS-11 – Same as Service Channel 1
• Service Channel 3 (64 kb/s channel) – can be used to carry 4-wire audio, or MCS-11
fault alarm information
