7. FEATURES
Global Features
• TDMoP Interfaces
o DS34S101: 1 E1/T1/serial TDM interface
o DS34S102: 2 E1/T1/serial TDM interfaces
o DS34S104: 4 E1/T1/serial TDM interfaces
o DS34S108: 8 E1/T1/serial TDM interfaces
o All four devices: optionally 1 high-speed E3/DS3/STS-1 TDM interface
o All four devices: each interface optionally configurable for serial operation for V.35 and RS530
• Ethernet Interface
o One 10/100 Mbps port configurable for MII, RMII or SSMII interface format
o Half or full duplex operation
o VLAN support according to 802.1p and 802.1Q including stacked tags
o Fully compatible with IEEE 802.3 standard
• End-to-end TDM synchronization through the IP/MPLS domain by on-chip, per-port TDM clock recovery
• 64 independent bundles/connections, each with its own:
o Transmit and receive queues
o Configurable jitter-buffer depth
o Connection-level redundancy, with traffic duplication option
• Packet loss compensation and handling of misordered packets
• Glueless SDRAM interface
• Complies with MPLS-Frame Relay Alliance Implementation Agreements 4.1, 5.1 and 8.0
• Complies with ITU-T standards Y.1413 and Y.1414.
• Complies with Metro Ethernet Forum 3 and 8
• Complies with IETF RFC 4553 (SAToP), RFC 5086 (CESoPSN) and RFC 5087 (TDMoIP)
• IEEE 1146.1 JTAG boundary scan
• 1.8V and 3.3V Operation with 5.0V tolerant I/O
Clock Synthesizers
• Clocks to operate the TDMoP clock recovery machines can synthesized from a single clock input (10MHz,
19.44MHz, 38.88MHz or 77.76MHz on the CLK_HIGH pin)
• Clock to operate TDMoP logic and SDRAM interface (50MHz or 75MHz) can be synthesized from a single
25MHz clock on the CLK_SYS pin
TDM-over-Packet Block
• Enables transport of TDM services (E1, T1, E3, T3, STS-1) or serial data over packet-switched networks
• SAToP payload-type machine maps/demaps unframed E1/T1/E3/T3/STS-1 or serial data flows to/from IP,
MPLS or Ethernet packets according to ITU-T Y.1413, Y.1453, MEF 8, MFA 8.0.0 and IETF RFC 4553.
• CESoPSN payload-type machine maps/demaps structured E1/T1 data flows to/from IP, MPLS or Ethernet
packets with static assignment of timeslots inside a bundle according to ITU-T Y.1413, Y.1453, MEF 8, MFA
8.0.0 and IETF RFC 5086.
• AAL1 payload-type machine maps/demaps E1/T1/E3/T3/STS-1 or serial data flows to/from IP, MPLS or
Ethernet packets according to ITU-T Y.1413, MEF 8, MFA 4.1 and IETF RFC 5087. For E1/T1 it supports
structured mode with/without CAS using 8-bit timeslot resolution, while implementing static timeslot allocation.
For E1/T1, E3/T3/STS-1 or serial interface it supports unstructured mode.
• HDLC payload-type machine maps/demaps HDLC-based E1/T1/serial flow to/from IP, MPLS or Ethernet
packets. It supports 2-, 7- and 8-bit timeslot resolution (i.e. 16, 56, and 64 kbps respectively), as well as N x 64
kbps bundles. This is useful in applications where HDLC-based signaling interpretation is required (such as
ISDN D channel signaling termination, V.51/2, or GR-303), or for trunking packet-based applications (such as
Frame Relay), according to IETF RFC 4618.
