PDH and SDH DIPs

• DIP, digital path– PDH 2 Mbit/s for ETSI (E1)– PDH 1,5 Mbit/s for ANSI and PDC (T1)– Implemented on ETC5 in GDM

• SDIP, synchronous digital path– SDH 155 Mbit/s for ETSI, ANSI and PDC (STM-1)– Implemented in ET155-7 in GDM– Implemented in ET155-1 in GEM– 63 E1 DIPs per STM-1– 84 T1 DIPs per STM-1

Rev A 2003-12-18 9

The Digital Path (DIP)

• Commands to define DIPs:– DTDII:DIP=dip,…;– DTDIE:DIP=dip;– DTDIP:DIP=dip…;– DTBLI/DTBLE:DIP=dip;

• Commands to handle DIP Initial Data:– DTIDP:DIP=dip;– DTIDC:DIP=dip,…,…;

SNT in AXE810

Switching Network Terminal

Digital Path

Rev A 2003-12-18 27

Two types of SNTs in AXE810

• SNTs in GEM– ET155-1– ECP5– TRA

• SNTs in GDM connected to DLEB or DLHB– MUX34 = DLEB

ET155-7 from BYB 501 1.4– MUX3 = DLHB

Hardware reused from BYB 501 1.4, e.g. M-AST, ETC5 and PDSPL

Dynamic MUP Allocation DL34 Interface

• The DL34 interface is introduced in AXE810• It is possible to allocate different devices a number of

MUPs in steps of 128. – 2048 2K (largest selectable)– 1024 1K– 512 0.5K

• Maximum for a Switch Board (XDB) is 16K• DLEB use a fixed number of MUPs (2048)

– Maximum of 8 DLEB per GEM

• NTCOI parameter MODE sets the number of MUPs.
