Note: If you set a link for E1 mode, the data on channel 24 is not inverted. The external carrier must map the channels to the CEPT link.

Connecting to MSDN CEPT Links (E1 Mode)

Channel mapping is required to connect with CEPT links; the external carrier must map the channels to the CEPT link. If you set a link for E1 mode, the data on channel 24 is not inverted. Channel 24 of the E1/T1 (DS1) link must be mapped to channel 16 of the CEPT (E1) link.

You must dedicate channels to either voice or data transmission. You must also inform the carrier which channels are used for data transmission and which channels are used for voice transmission. The carrier must program the voice channels for A-law to m-law conversion. Data channels and the common channel signaling (CCS) channels must NOT be converted.

The datasets for the dedicated data channels of a link must be set for 64kbps operation. You must also reverse the polarity of the dataset Tx and Rx leads at one of the PBXs. For consistency, always reverse the dataset leads on the system with the E1/T1 (DS1) Formatter card.

Basic Rate Interface (BRI) Card

The BRI card provides an interface between either six (6-circuit card) or fifteen (15-circuit card) ISDN basic rate interface ('U'-bus) circuits and one CEPT circuit. The card converts the Euro-ISDN or North American National ISDN-1 and ISDN-2 protocols used by the BRI circuits to the DPNSS protocol used by the CEPT circuit.

The connections to and from the BRI card are made via the CEPT Interface Assembly mounted at the back of the DSU cabinet. These connections are:

DPNSS Tx to the CEPT Interface Assembly Rx port via a BNC to BNC connector

DPNSS Rx to the CEPT Interface Assembly Tx port via a BNC to BNC connector

BRI 'U' bus tip-and-ring pairs via a D-type to Amphenol connector

MMI connection to the configuration terminal via an RJ45 to D-type connector

Provision for an RJ45 Ethernet port as a future development of the card.

Note: The BRI card, Release 2, supports both User and Network Termination; for European installations only.
