ATM Switching: RCHATM Switching: RCH

Use of the ATM technique for narrow-band switching (“Composite” ATM)

Compatibility ensured with existing technology• Defense: duplication mechanisms as for RCX• Same interfaces with SMT, CSNL, SMA …

Compactness• Huge reduction of boards and racks• Reduced Power consumption



Since the Alcatel 1000 E10’s ATM matrix is a cell switching device, 64 Kbit/s channels to/from ATM cell adaptation is performed

ATM Switching: RCHATM Switching: RCHComposite ATM (TCA 1/2)Composite ATM (TCA 1/2)

Converting voice circuits into/from ATM cells must be delay free All Time slots bound to the same destination are loaded in the same ATM

Virtual Circuit (VC) every 125 s (no packetisation delay)

One or several VC (depending on traffic load) lead to that destination (the VCs to cross the ASE are established dynamically)

Cell delivery time is mastered by the CBR AAL1 service category

To line up with the switch internal connectivity, the RCH also uses the LR as input/output link format:

• 8 bits speech or data information• Supplementary check bits to provide per channel protection

through the RCH.

16 x 622 Mbit/s ATM ports for the switching

The ASE board (ATM Switching Element) is the basic ATM matrix• 16 x 622 Mbits input/output ports (10 Gbit/s)

It enables connecting:• PCMs through the TCA (narrowband)• High bit rate links (for new TU)
