BCM 4.0 Networking Configuration Guide
• Originating Line Identification (OLI) for incoming and outgoing calls:
— For incoming calls, the Calling Line Identification (CLI/CLID) information is displayed to
the user on telephones with line display. This must be configured in programming.
— For outgoing calls, the directory number of the originating party is sent out as OLI.
• Terminal Line Identification (TLI) for incoming and outgoing calls. Referred to as Called Line
Identification.
• Selective Line Redirect (SLR) and External Call Forward (ECF) implemented on calls
between DPNSS 1, and BRI/PRI, DASS2, and analog lines.
• These remote access features are supported on DPNSS: DDI, line pool access code,
destination codes, and remote page feature codes.
DPNSS to Embark connections
DPNSS lines connected to an Embark switch perform call redirection/diversion using the Call
Forward feature to create a tandem link back to the switch. Since this is different from other
switches, you must select the type of switch DPNSS will be connecting to when you do module
programming.
Before you program Call Forwarding, ensure that:
• Both real channels and virtual channels are provisioned.
• Destination or line pool codes are programmed for the DPNSS to Embark link.
Also, during programming for Call Forward No Answer and Call Forward on Busy, when you
enter the Forward to: digits, the system performs a validation check with the switch on the
number. (Configuration > Telephony > Sets > Active Sets > Line Access > Properties tab)
