Description:
The SLC (Small Line Card) is a 1”x1.2”, ultrasmall OEM timing module integrated into line interface cards of telecom network equipment such as long haul, core and access switches, cross connects, transport equipment, SONET/LAN convergence and so forth. The SLC provides all of the timing functions wherever OC-N interfaces are used and installed in conjunction with other Stratum clocks such as TeraSync’s Stratum 2, 3, and 3E product lines. The SLC provides a full timing solution for equipment incorporating an OC-N interface, complying with Telcordia GR-253-CORE and ITU-T Rec. G.704/G704. The SLC meets the relevant performance and functional requirements necessary for timing modules installed in line interface cards.
