ATM switching equipment having a switching network

An ATM switching equipment comprising:

• a switching network;
• an input interface unit including an input processing unit;
• an output interface unit including an output processing unit;
• a microprocessor;
• a server switching unit comprising:
• an AAL2 switcher that is connected to the switching network via a first interface;
• an input processing unit to which said AAL2 switcher is connected;
• and
• an output processing unit to which said AAL2 switcher is connected;
• said switching equipment being configured to write a new VPI/VCI information, including VP/VCI bits, for a further connecting section into cells of arriving data streams upon utilization of routing tables,
• said AAL2 switcher being configured for simultaneous processing of a maximum plurality of incoming connections, an AAL2 routing list being provided for each of said incoming connections;
• said AAL2 switcher being connected to said switching network without requiring recognition of all VPINCI bits in the AAL2 switcher;
• and
• said microprocessor limiting the number of bits representing VPINCI bits from among VPI/VCI bits transmitted in a header of ATM cells to be interpreted according to a number of ATM connections available for processing, as indicated in said AAL2 routing lists, so that said first interface considers corresponding VPI/VCI bits.
