6 You can only replace (spare) a circuit pack with a circuit pack with the
same product engineering code (PEC).
7 1+1 MSP, SNCP, and unprotected traffic protection schemes are available.
The STM-1/4 interfaces must be provisioned in a MSP group for 1+1 MSP
protection, or in unprotected mode for SNCP or unprotected configuration.
8 Only the 8x10/100BT L1, 2xGE L1, 28xE1/DS1, 3xE3/DS3 and 2x155M
circuit packs can be inserted in the tributary slots (slots 4, 5, 8, 9).
Note: When the tributary slots are not equipped with a circuit pack, a filler
panel must be installed.
9 The STM-1/4 and GE interfaces use small form-factor pluggable (SFP)
modules. Each active port requires a SFP module, which are ordered
separately. Dust covers for the SFP positions are included with the circuit
packs, therefore, dust covers do not need to be ordered for unequipped
ports. A maximum of 2 SFP modules are required for each STM-1/4 and
GE circuit pack.
10 The 2x155/622M aggregate and 2x155M tributary circuit packs support
optical (o) and electrical (e) SFP interfaces at the STM-1 line rate. The
2x155/622M aggregate circuit pack supports only optical SFP interfaces at
the STM-4 line rate.
11 The 28xE1/DS1 circuit pack require the appropriate I/O interface cabling.
The default impedance for the E1/DS1 interfaces is 120/100 ohm. The
E1/DS1 interface uses a 64-pin Telco connector. Conversion for E1
services to 75 ohm unbalanced interface can be achieved using the 75 ohm
BNC termination panel.
12 In a rack mount installation, it is recommended to install the 75 ohm BNC
termination panel directly below the OME6130 shelf. If more than one
termination panel is required (for converting impedance of ports on the
28xE1/DS1 circuit packs), stack the termination panels below the
OME6130 shelf.
