• PSU2 uses three types of protocol handlers:

– FRPH (PH4/PH22) - terminates packet pipes

– PHV - converts encoded and compressed voice and/or data packets to/from PCM samples

– PHA - interconnects packet switching units

• Each shelf contains:

– 16 circuit board slots

– Access to 768 minus 1 control time slot leaving 767 configurable time slots


OVERVIEW OF LUCENT 5ESS DCSPSU2 Shelf (Basic)PSU2 Shelf (Basic)


OVERVIEW OF LUCENT 5ESS DCSPH22(FRPH)PH22(FRPH)

FRPH on the PH22 supports:

•240 PPCUs

• Up to 64 Packet Pipes (1-DS0 PP)

• 64 Time Slots per FRPH

•DF2 is required to be used on all PSU2 shelves equipped with PH22s

• Maximum active FRPH-PH22s on a PSU2 shelf is 11

• The number of PPs which terminate on a PH22-FRPH Increases due to the increased number of DS0s (64) and number of PPCUs(240)

•At Reliance, Two 15 DS0 PP and one 13 DS0 PP are terminated on PH22-FRPH




OVERVIEW OF LUCENT 5ESS DCSPHV5 CardPHV5 Card

Protocol handler for voice (PHV):

– Part of PSU2

– Transmits and receives packets through the FRPH

– Converts voice packets from cell into 64 kbps PCM voice and viceversa

– Supports 3G HSPD channels on RLP3 circuits


OVERVIEW OF LUCENT 5ESS DCSDPH(PHV5)DPH(PHV5)

•DF2 is required to be used on PSU2 shelves equipped with PHV5s

• Dynamic Allocation of Vocoders (DVA)

• Multiple vocoder algorithm on a PHV5

– 13kbps and EVRC (CEV13)

• The maximum number of PHV5s that can beequipped per PSU2 shelf is 11

•DPH on a PHV5 supports up to 64 3G-1X HSPD calls (at the fundamental data rate of 9.6kbps)

• The DPH supports simultaneous forward andreverse bursts at discrete data burst of 2x, 4x,8x and 16x the fundamental data rate.

OVERVIEW OF LUCENT 5ESS DCSPHAPHA

Protocol handler for asynchronous transfer mode (PHA):

– Provides point-to-point connection between PSU2s or from a PSU2 to an ATM

– Does not use PSU2s time slots

• Functions: Direct Link node(DLN 60)

– Provides message routing functions for all inbound SS7

and ANSI-41 messages

– Routes incoming X.25 inter-MSC messages

– Routes incoming 5ESS DCS messages

• Engineering:

– Two DLNs - one active (Home) and one standby

– Only one DLN is active at a time; the other DLN is a

Hot spare

• No data links



Node Type Maximum Configuration

CDN 12 or 24

DLN always 2 (1 pair)

SS7N 128 (112 ANSI-41, 16 ECP to 5E)

RPCN always 2 (1 pair)

EIN 1 per AP






OVERVIEW OF LUCENT 5ESS DCSSS7 SS7 • CCS7 protocol - Three applications are used in

the FLEXENT / AUTOPLEX system:

– First is the ISDN user part (ISUP) with out-of-band signaling ISUP implements circuit related function including call setup

• ISUP is used in 5ESS. DCS and the PSTN signaling

– Second type is the ANSI-41

• ANSI-41 is for non-circuit related applications

• ANSI-41 is used as follows:

– Point-to-point signaling to other AUTOPLEX MSCs

– Signaling to signal transfer points (STP)

– The third type is Lucent proprietary signaling

Signaling System 7 Nodes (SS7N)

– The third type is Lucent proprietary signaling

• Used between the 5ESS. DCS and the ECPC
