1 Time Division Multiplexing
Oracle® designed the Time Division Multiplexing (TDM) functionality for companies planning to migrate from TDM to SIP trunks by using a hybrid TDM-SIP infrastructure, rather than adopting VoIP-SIP as their sole means of voice communications. The TDM interface on the Oracle® Enterprise Session Border Controller (ESBC) provides switchover for egress audio calls, when the primary SIP trunk becomes unavailable. You can use TDM with legacy PBXs and other TDM devices.
- Only the Acme Packet 1100 and the Acme Packet 3900 platforms support TDM, which requires the optional TDM card.
- TDM supports bidirectional calls as well as unidirectional calls.
- TDM operations require you to configure TDM Config and TDM Profile, as well as local policies for inbound and outbound traffic.
- The software upgrade procedure supports the TDM configuration.
- Options for the Acme Packet 1100 and the Acme Packet 3900 platforms include Calling-Line Identification Presentation (CLIP) and Connected-Line Identification Presentation (COLP).
- Options for the Acme Packet 1100 platform include the four-port Primary Rate Interface (PRI), the Euro ISDN Basic Rate Interface (BRI), and the Foreign Exchange Office-Foreign Exchange Subscriber (FXO-FXS) card.
Interface Requirements
PRI—Digium1TE133F single-port or Digium 1TE435BF four-port card.
BRI—Digium 1B433LF four-port card
FXS—Digium 1A8B04F eight-port card, green module (ports 1-4)
FXO—Diguim 1A8B04F eight-port card, red module (ports 5-8)
Notes
When you deploy either the Acme Packet 1100 or the Acme Packet 3900 in a High Availability (HA) pair, the active system cannot replicate calls between SIP and TDM to the standby system.
The Acme Packet 1100 does not support HA for the PRI, BRI, and FXO-FXS interfaces.
