DMS-100 Ringing System

Ringing in the Universal Edge 9000

The architecture of the POTS functionality in the Universal Edge 9000 (UEN)

borrows heavily from the LCM. This is because the time division multiplexing

(TDM) software functions the same as that of the LCM in the DMS-100

system. The UEN

• interfaces to an LGC, LTC, or RCC2

• provides redundancy down to the node level (for example, each unit in the

node can take over the mate unit’s call processing in the event of a failure)

• concentrates voice channels (that is, more in-service lines are supported in

UEN than there are voice channels to the host PM)

• supports World line card (WLC) POTS line cards

Each UEN DMS frame contains up to four physical UEN DMS shelves. Each

UEN DMS shelf consists of 21 card positions that contain up to:

• 16 multi-circuit line cards

• 2 TDM (voice) control cards

• 2 data control cards (future)

Slot 1 contains two half-height cards:

• one power input/output card

• one shelf interconnect card

Each UEN shelf consists of 16 line cards that offer voice service. The UEN

shelf also contains two TDM common equipment cards. The TDM cards are

redundant and able to support from 2-6 DS-30B connections in each shelf to

the host PM, for a maximum of 12 DS-30B in each frame.

Each line card with voiceband services has its own ringing generator. There are

no hardware resources present in the shelf to synchronize operation of these

ring generators. Hardware and software resources on the line card and at the

TDM interface cards monitor the operation of the ringing generator on each

line card to detect and report overload and failure conditions.

The following ﬁgure provides a front view of the UEN shelf assembly

showing slot assignments and line card / line su/jointfilesconvert/480876/bgroup numbering schemes.
