____________________________________________________ DS34S101, DS34S102, DS34S104, DS34S108
Supports single high-speed E3, T3 or STS-1 interface on port 1 or one (DS34S101), two (DS34S102), four
(DS34S104) or eight (DS34S108) E1, T1 or serial interfaces
For single high-speed E3, T3 or STS-1 interface, AAL1 or SAToP payload type is used
For E1 or T1 interfaces, the following modes are available:
For serial interfaces, the following modes are available:
All serial interface modes are capable of working with a gapped clock.
64 independent bundles, each can be assigned to any TDM interface
Each bundle carries a data stream from one TDM interface over IP/MPLS/Ethernet PSN from TDMoP source
device to TDMoP destination device
Each bundle may be for N x 64kbps, an entire E1, T1, E3, T3 or STS-1, or an arbitrary serial data stream
Each bundle is uni-directional (but frequently coupled with opposite-direction bundle for bidirectional
communication)
Multiple bundles can be transported between TDMoP devices
Multiple bundles can be assigned to the same TDM interface
Each bundle is independently configured with its own:
Each bundle can be assigned to one of the payload-type machines or to the CPU
For E1/T1 the device provides internal bundle cross-connect functionality, with DS0 resolution
Sophisticated TDM clock recovery machines, one for each TDM interface, allow end-to-end TDM clock
synchronization, despite the packet delay variation of the IP/MPLS/Ethernet network
The following clock recovery modes are supported:
The clock recovery machines provide both fast frequency acquisition and highly accurate phase tracking:

Unframed – E1/T1 pass-through mode (AAL1, SAToP or HDLC payload type)
Structured – fractional E1/T1 support (all payloads)
Structured with CAS – fractional E1/T1 with CAS support (CESoPSN or AAL1 payload type)
Arbitrary continuous bit stream (using AAL1 or SAToP payload type)
Single-interface high-speed mode on port 1 up to STS-1 rate (51.84 Mbps) using a single
bundle/connection.
Low-speed mode with each interface operating at N x 64 kbps (N = 1 to 63) with an aggregate rate of
18.6Mbps
HDLC-based traffic (such as Frame Relay) at N x 64 kbps (N = 1 to 63) with an aggregate rate of
18.6Mbps).
Transmit and receive queues
Configurable receive-buffer depth
Optional connection-level redundancy (SAToP, AAL1, CESoPSN only).
Adaptive clock recovery
Common clock (using RTP)
External clock
Loopback clock
Jitter and wander of the recovered clock are maintained at levels that conform to G.823/G.824 traffic or
synchronization interfaces. (For adaptive clock recovery, the recovered clock performance depends on
packet network characteristics.)
Short-term frequency accuracy (1 second) is better than 16 ppb (using OCXO reference), or 100 ppb
(using TCXO reference)
Capture range is ±90 ppm
Internal synthesizer frequency resolution of 0.5 ppb
High resilience to packet loss and misordering, up to 2% without degradation of clock recovery
performance
Robust to sudden significant constant delay changes
