2xGE L1 circuit pack
The 2xGE L1 circuit pack can be installed in the tributary slots on the
OME6130 chassis to offer Gigabit Ethernet services.
Figure 4-9 shows the
faceplate of a 2xGE L1 circuit pack.
The 2xGE L1 circuit pack supports pluggable optical transceivers for the two
GE interfaces. The GE optical interfaces use small form-factor pluggable
(SFP) interfaces to deliver optical rate and reach flexibility on a per port basis.
The GE optical interfaces use SFP modules for short reach (SX) and
intermediate reach (LX) applications.
Figure 4-9 shows the GE optical
interface ports on the 2xGE L1 circuit pack.
The PEC for the 2xGE L1 circuit pack is listed in Table 4-8 .

2xGE L1 functionality overview
The 2xGE L1 circuit pack consists of two entities (client facing and line
facing):
• client facing interfaces referred to as Gigabit Ethernet ports
• line facing (mapped for transport via SDH containers) interfaces referred
to as WAN ports
The 2xGE L1 circuit pack supports the following:
• supports the transport of up to two (2) Gigabit Ethernet services ports
• mapping of Gigabit Ethernet to/from SDH containers via Framed GFP at
following levels:
— VC3 and VC4 operating granularity
— contiguous concatenation at VC4
— virtual concatenation (VC3-nv, where n = 1 to 12 and VC4-nv, where
n = 1 to 4)
